Remember, its TWO 460 1GB cards that come close to matching the performance of one 5970. In this scenario I'd much rather spend +£100, get the 5970 and OC that.
what the heck, a hd 5970 is just two 5870 slapped together therefore subjected to any weakness inherent to sli/crossfire so what is wrong with 2x 460 GTX sli (if your motherboard supports sli) that offer the same performance, but if you have plenty money though whichever floats your boat is fine i guess, for others though the 100 quid difference could afford another improvement to your system such as an intel SSD or better sound card
FPS is king. You go look at a 5970 review where they OC it then compare it to your precious 460s your trying desperately hard to defend. Raw numbers speak volumes, the 460s are good performers at their price, but a 5970 they are not.
i guess some of you guys are right the 460's did lead to price drops.....on the 470's lol
299-330 will get you one now before the weekend they were $330-350.
http://www.newegg.com/Product/Produc...82E16814127501
only if the 480's would lower to around $430 or so.
*edit checking the 480 prices they are dropping too!!
$460ish before $20 mir(alot of brands)
looks like nv has tightened up the $200ish and $300ish market.
I think there is also the issue of comparing graphics CARDS, not # of GPUs. I know a ton of people will jump on this so-called logical fallacy, but I see nothing wrong with comparing the performance of a graphics card that fits into ONE PCI-E slot. This is why the 5970 is still the best graphics CARD.
Best???? It's about as fast as a pair of GTX 460 1GB's which are two GPU's still just like the 5970 (2x GPU), yet costs 50% more. Where's the good in that?Quote:

if you are talking about oc performance then 2x460gtx 1GB oced would still match hd 5970 oced. of course the 5970 is skill the king of single card but as an perf/price solution it is not.
And i see nothing better than a videocard that fit in every case. 5970 don't fit or barely fit in many cases.Quote:

And for 250$ you can buy a good case, a good cooler, a good Psu and may be even a HDD.
You people don't learn anything from the economic crysis, why to spend so much more money for almost nothing more ?
( two Palit Platinium at 800/1600/4000 are i think equal to 5970 ).
More to this Nvidia will launch dual GF 104 card in this summer so buying now a 5970 is like throwing to garbage 250$.
Also 2 GTX 460 are easy to sell everytime you want, one by time, 5970 is more expensive is harder to sell again.
From two GTX 460 will be more easy to upgrade in the future.
And look at this, GTX 460's can do 950 core, 4600memory> with a little voltage posiible to done on the majority of GTX 460s.

Impressive picture Xdan, I'll be happy as a pig if I can get my 1GB SLI GTX 460 setup to run at those speeds :D.
your right, thats why im happy with my 4850 xfire, less than 200$ and i play every game i own at 1920x1200, high details, 16xAF and 2-4xAAQuote:

hmmmm still not sure my 465 or 460 is the real price/performance king. need to team them up for F@H after summer and compare :D
The 465 will not win in power consumption, but will likely win in terms of PPD due to a more efficient architecture. It depends on the implementation of course, but I'd wager the current WU's aren't optimized well enough for the 460's slightly different arch.Quote:

Also Gigabyte it's not better than reference. Reference cooler is very good, so you can buy without any regrets reference cards.
Now, Gigabyte GTX 460OC 1gb, custom cooler.

Was there any info on the galaxy being any better or worse with its custom cooler? Thanks again for reposting those shots.
Why are people comparing GTX460 to HD5850s? they are alot cheaper ???
Your not fooling anyone. Your just trying to crap on this launch as much as possible. The press is almost universally praising the release of this card. No one needs to defend their purchase of a gtx 460 because the press has already done so. Alot of reputable websites are saying the exact same thing in that SLI performance of the gtx 460 is impressive.Quote:

I don't think your fooling anyone changing your sig, I am pretty much everyone that have seen your posts knew you had 5830 in xfire in your sig prior to the release of the gtx 460. You sound really really bitter honestly.
Its no doubt that the 5970 is the fastest graphics card that takes up one slot, for certain people that don't have a SLI capable MB, this means alot. But for people that do have boards capable of SLI, gtx 460 in SLI provides much better bang for the buck.
Yep... priced like 5770 on newegg if you count the just cause 2 freebie now, yet beats 5850 easily when comparing overclock to overclock. One hell of a card!Quote:

Add OCing to the equation and it's a no brainer. The 460 leads the Fermi line in value AND thermal efficiency. Reviewers are commonly hitting 850MHz+ core speed without even raising the paltry 40% fan speed or core voltage.
Wonder if we'll see 1ghz cores with a little added voltage + fan speed in software :eek:.
Will the 470 water block fit the 460? I wonder if these will have a higher ceiling under water...Quote:

It's annoyng that reviewers don't put pictures with the GPU voltage controller of every card( lab501 team do that).
From what is known all GTX 460 cards use as controller of GPU voltage NCP5388 fabricated by ON Semiconductor ,
used also on GTX 470, GTX 480 and GTX 465 cards on wich voltage adjustment worked even on custom pcb cards from Palit/Gainward/Galaxy.
So, relax voltage adjustment work 99% sure on every GTX 460.
But not be so entuziast there are raports than at 1.1v the GPU VRM enters in protection(or the GPU itself?) and lower the frecuency and voltage.
For more than 1.1v(max alowed by Msi Afterburner) you need to do an hardware mod.
But is is possible that 1.08v to be enough to reach 1000Mhz. Heat isn't a problem with fan at 70% on reference you will not reach more than 75-78C
The question is how good the GF 104 scales with voltage.
http://lab501.ro/wp-content/uploads/..._5-430x580.jpg
Also a picture of Gigabyte GTX 460OC cutom VRM, may be better than reference?
http://lab501.ro/wp-content/uploads/...10-580x385.jpg
Awesome Xdan, thank you for the information.
But still is better to wait 4-5 days more because i saw that on newegg Palit GTX 460 1gb stock finished so we must have some information on a couple of days. If you can see the actual video card the ON controller is easy to see it's placed on back of the pcb( that larger chip) near the the cooler screws.
Unfortunately guru3d posted a low resolution picture....

Yes, the 470's are less thermally efficient, however he did bring up a good point, considering in the real world you now can grab a 470 for $279...Quote:

Just because we need a minimum of 70% fan to achieve stock 480 +/- levels while gaming on a 470 at 80c(825-850core), doesn't make it the pos of a card you're making it out to be.
Also, where are the reviews of the OC'ed 470's and 480's and I'm not talking about the ones that obviously skew the results.
For the majority of people, the 460's are going to be a good thing, there is no reason to over hype the hype....
*edit*
With that being said, I'm even considering ditching my 470 and down grading, I'm starting to get tired of babysitting temps and would like something new to play around with.

thanks for the info you guys
any1 yet go sub zero with the 460 cards?
i wanted a heads up if possible...if not i'll report back when the card comes today.
help with hard mod(ect.)or read points is good also
They have it in-stock now for $230 with a free just cause 2 coupon, but the warranty is supposed to be iffy in terms of where you send the card to and conflicting info as to the length (1-year vs. 2-year), so I'm going to just hold out for an eVGA 1GB GTX 460 pair myself for SLI.Quote:

Bah, TigerDirect changed my order to backorder with no ETA... I ended up canceling and going for in-stock Gigabyte 460 1GB's @ newegg... it costs more but they're in-stock and no worries on fan noise like with the Galaxy (plus 3-year warranty instead of 2, which is always good). I'll let you guys know some performance #'s and what kind of overclock I can get out of 'em once they come... ETA beginning of the week :D.
Would i buy 1GB model with "factory overclocked" or just "non overclocked" ?
Non overclocked, OC yourself for a few cheaper bucks!
Well that's good for you since the Galaxy/KFA2 GTX 460 definitely seem to be noisy as hell :D :Quote:

Holy cow, you're not kidding... thanks for that link, I'm REALLY glad I switched now even though it's going to cost me more. Between the noisy fan and uncertain ETA on the Galaxy I'm quite pleased I went for the Gigabyte 1GB model now with the dual-fans, which are good per those charts.

Nice review of a GTX 460 1GB @ 925core/4200mem with voltage adjustment, compared to Gainward Golden Sample GTX 470 1280MB @ 650core/3400mem (and other cards).
NCspec can you run them in SLI? wanna see ur vantage scores :D
http://images.tweaktown.com/content/3/4/3410_41.png
This graph really paints the picture. We're really able to pick off the Gainward GTX 470 Golden sample here and at the same time we pass the HD 5870 2GB, normal HD 5870 and GTX 465 at 860MHz core as well. You can see for yourself we're really not all that far from the overclocked GTX 470 and the stock GTX 480.

Newegg sub-boss "UPS Man" downed; The Gigabyte GTX 460 1GB cards looted!
http://www.trizzeo.com/gigabytegtx460boxes1gb.jpg
Got my cards installed earlier and have had some time to play with them a good bit now... my motherboard allows for either PCI-E 2.0 x16 when sandwiched, or PCI-E 2.0 x4 with breathing room for the cards. I first tried sandwiched (note that the fans actually end up taking the full 2 slots even though the pictures don't look it) but the top card was running a full 25c higher than the bottom (around 55c vs. 80c top/bottom during a game). So, I am trying them with the x4 speed, and the temps are virtually identical on each card (within 2-4c now) at full load after gaming awhile.
The good news for me is they ARE very quiet.... I have it at 82% fan speed and it is as quiet as the rest of my case fans for this Gigabyte 1GB pair (dual fans). Color me impressed on that. The other good news is that they run like gangbusters in the only game I've tested so far, BattleField Bad Company 2. Also, I was able to flash them with an MSI BIOS that was modded to allow up to 1.212v (thank you NCspecV81 of XS) instead of the 1.087v normal cap in Afterburner.
Running at 2560x1600 8x CSAA, 16x HQ Anisotropic Filtering (AF), max in-game settings with HBAO on in DX11 mode *AND* Transparency MSAA enabled in the control panel, my overclocked Gigabyte 1GB GTX 460's in SLI are pulling off around 55minimum (usually 60), and 75-80 average FPS for me across the different maps of BFBC2. This is, mind you, with them running at PCI-E 2.0 x4 instead of the full x16, which means around a 10% performance loss from what I have read.
The bad news is I can't nail down a stable overclock yet like I was hoping to that is sky-high. So far I am running 880mhz core on both cards with 3900mhz on the memory... not quite as high as I was looking for, and this is with 1.100v on the cores. They currently max out at around 76c for the pair at these speeds after an hour+ of gaming in BFBC2 with the 82% fan speed (note again that it REALLY is quiet, these fans don't get loud at all :) ).
The silver lining here, however, is that I am able to get 950+mhz on the core with 4000mhz-4100mhz memory with 1.212v, but the temperatures go up into the mid-high 80's... I haven't fiddled enough with lower voltages and various clock combos yet to see if I can get a fully gaming-stable setup in the low-to-mid 900's, though it should be possible since some report doing it with single cards. I'm not sure if I'm just running into a barrier due to SLI or what, yet, but we'll see.
I really must say how quiet these are, again, even at 82%... it sounds like my eVGA GTX 470 did at 45-50% fan :D.
I'll update the thread with some benchmarks later if people want them, and any further progress I make on overclocking. Maybe I am expecting too much in SLI off of these things for overclocking, but I'm looking forward to pushing em hard :p !
goodluck with the cards GT:)
should make a good gamig rig if thats what floats your boat:D

Doh, that's still one hell of a clock Cowie :). I had it in my head that I'd get higher than I have with my cards in SLI... so I feel disappointed even though it games amazingly well :p: . My main purpose for them is gaming, so it works nicely... secondary is development, with benchmarking being about as far back as you can go other than to compare my own rig to itself vs. the single 470 I had.
Have you tried the MSI bios or just the evga one?
If you meant that question to me (not sure if it was addressed to cowie or not), I tried the MSI one only.
1. Try each card single on PCIE 16X to see what it can do each card on their one.Quote:

This is, mind you, with them running at PCI-E 2.0 x4 instead of the full x16, which means around a 10% performance loss from what I have read.
The bad news is I can't nail down a stable overclock yet like I was hoping to that is sky-high. So far I am running 880mhz core on both cards with 3900mhz on the memory... not quite as high as I was looking for, and this is with 1.100v on the cores. They currently max out at around 76c for the pair at these speeds after an hour+ of gaming in BFBC2 with the 82% fan speed (note again that it REALLY is quiet, these fans don't get loud at all ).
2. I think that the 4X electrical slot cand reduce the capability of overclocking, i mean at 4x i think the power through the slot is reduced too so instead the card might used more power from the power conectors and it might have a negative efect.
3. From what is known by now all chips can do 830-840Mhz/4000(core/memory) with stock voltage. 1.1v it's much for 24/7. Try 1.06v it's more acceptable. Try to use more fans in the case(than you have allready)
Unfortunatelly i think that when they are sandwhiched the bottom card intake all the hot air from the first card...
Xdan, your thoughts are very possible and interesting... I'm trying them sandwiched again and will up the fan speeds (which I hadn't the first time), and then test them individually if the overclock does not improve. Especially #2 piques my interest as a possibility.
Thanks Xdan... I tried both of them individually, one is crashing at stock speeds when played with for awhile while the other is already going 875+ core with 1.037v without issue and 3850 mem. I'm RMA'ing the defective one... replacement would be here tomorrow but they're out of stock for cross-ship right now.
The good card has been working at 922core/4000mem with 1.100v, will tweak it further then try SLI again once my replacement comes.
I don't think +1.1V on a 40nm GPU die is much for 24/7. I'm not 100% what the stock voltage was on these card under 3D mode, but 1.1 is easy in mine opinion.Quote:

Can you replace it with another brand of GTX 460? I think that you would have better temperatures with one card as reference, because reference cooler drops less hot air inside and much more outside the case than Gigabyte cooler.Quote:

Using the reference card as top card and the Gigabyte as bottom i think can improve the temperatures in SLI. And from lab 501 the reference cooler( 60-62C with fan at 60%) is better even than Gibabyte's with 4-5C.
On neweeg Sparkle 1gb reference is on stock.

The fins are oriented to conduct the air outside the case and the pass from thin fins and more dense fins to larger fins and less dense has the role to make air turbulence good for cooling.
The BIOS I have was edited by NCspecV81 and can be downloaded from his post over on OCN as an attachment: http://www.overclock.net/nvidia/7819...ap-unlock.html
I'm both happy and disappointed... because I couldn't fully stabilize any real overclock with one of the cards being defective (which I'm disappointed with it coming in bad), but I'm happy that I figured out the issue and will get more speed in the end plus a fully stable system :).
EDIT: Yeah, Xdan, I could do a different brand... prefer to have two matching, though, and I'm unsure of Sparkle's warranty quality... tempting though.
The waranty is lifetime, of course that i would have recomended Evga EE(all air external exhaust) but it seems that from 2-3 days there are not any Evga.s GTX 460 in stock.

Than just raise the fans speed to 70-80% if it doesn't disturb you.
Welcome :)... FYI the modded BIOS, at least on my Gigabyte card, allows me to change fan speed inside of Afterburner from 0-100% with proper, full functionality :D.Quote:

You cant say Celeron next to a 460 you'll make it cry :p: Even though back in the day I saw quite a few 300 cellys hit some insane speeds :cool:
Funny thing is, I was thinking of making a thread for my OC result with the something similar to the following title right as I was testing my pair of 1GB 460's:Quote:

My non-defective card is sitting very happily at 920mhz core/4000mhz ram so far, haven't upped voltage further than 1.100v for that and it's rock-stable. It's loading at around 72c, so I probably have a bit more room if I really wanted. Still, I think I'll leave it at that for now likely and try to get my 2nd card for SLI to those speeds once it's arrived... then push harder if I still have thermal room.
I'd be interested to know if increased GPU voltage helps with memory OCs. One thing I'm concerned about with the 460 is it being bandwidth stricken. I've noticed it a lot the mem not OCing well and if I'm not mistaken with nVidia GPUs (I'm rusty) the IMC is integrated on the GPU, correct?
It did with my GTX 470... voltage helped raise core and/or memory, but there was a definite correlation where one would cause the other to need to be lowered to become stable again... and yes that is correct as far as I know, the IMC is integrated on the GPU for nV chips.Quote:

You got me curious, Ket... so I dropped core to 900mhz, threw RAM up to 4400mhz, and for about 15 minutes it's been stable so far... definitely a performance boost over 922/4000, too :eek: . I'll do some benching later if it stays stable.
EDIT: 1.112v seems stable at 900c/4400m, 35 minutes of BFBC2 so far, will run it thru awhile and make sure all's well with Kombustor/etc. later. If it stays stable I'll do some benches.
So I did some Just Cause 2 testing on "The Dark Tower" bench to see how clocks affected things. The benchmarks each last 2 minutes. Here's some data.
TEST RIG: i7 920 @ 3.72ghz HT enabled, 6GB DDR3 @ 8-8-8 2T 1563mhz triple-channel, 256GB SSD (Indilinx Barefoot w/ Samsung NAND), X-Fi XtremeGamer, Gigabyte GTX 460 1GB.
All tests @ 2560x1600 with 8x CSAA w/ Transparency, 16x HQ AF, maxed in-game settings with Bokeh filter off.
For grins, 940c/3800m @ 2x AA resulted in a framerate of 27.17/second.Code:CORE ---------- MEM ---------- FPS
_______________________________
900 ---------- 3600 ---------- 23.98
900 ---------- 3900 ---------- 23.95
900 ---------- 4200 ---------- 24.48
900 ---------- 4400 ---------- 24.25
940 ---------- 3600 ---------- 24.63
940 ---------- 3800 ---------- 24.84
940 ---------- 4000 ---------- 25.05
Well... I'm sort of surprised. For the 940 tests I raised voltage to 1.125, for the 900 tests all ran at 1.112v. It seems that I may be CPU bottlenecked, since the results are all SO close together. I may try dropping my CPU speed to something like 3.2ghz and see how things are affected... or Vantage on Extreme pre-set (I hate how long it takes :p: ). Temperatures peaked at ~74c during a long session (1hr) of BFBC2 @ 1.112v and 900c/4400m, high fan percentage but still very quiet (just a light, gentle whoosh of air, I can barely hear it above my other fans which are ~25-27db ones, this is at 92%!!).
