Gigabyte GTX 460 SOC is on newegg at 219$,http://www.newegg.com/Product/Produc...82E16814125345
815/4000, 0.4ns memorys, 6+2VRM phases, 5870 cooler, a good choise at the middle.
It can go beyond 6870 stock performance...

seems OCed 6850 offers good value compared to OCed 6870

lets find what manufacturers have add better cooler for 6850 without increasing price much

6850 in crossfire, overclocked, likely is the best buy this decade.

I think that Asus Directcu is good also for little overvolt:

But I prefer Gigabyte HD6850 :)

Everyone can't wrong with a pair of HD6850 or GTX460 1GB overclocked for 350$. I just waiting some HD6950/HD6970 bench and choose before Christmas ;)

Radeon 6850 could run fine with 6870 BIOS

"For those of you excited about the possibility of 'unlocking' your HD 6850, it's not going to happen; the disabling is done at an ASIC level, not BIOS."

read the foot note

** update -- as it is right now looks like a BIOS update is not possible and that the extra shaders are dealt with at ASIC level.

Gigabyte has a 6850 custom pcb, dual fan windforce, just like GTX 460 OC cooler. Price is as reference, 179$.

xdan, it looks good.. as usual, it itched too much in my hands and did click order button on a cheapest card which was available :D gigabyte seems be slow coming in stock in Europe.

if it was me, i would rip those fans off and put some strong case fans on :D

indeed crossfire 6850 is very good buy. the same class in 5970 or better ;)

I mean, there's models of the GTX 460 that match a GTX 470 in performance out of the box. We've had the ability the match the $350 price range at $200 for awhile now.

So no, I'm still not excited, because frankly this card isn't doing anything we haven't already seen since the summer. I just expect more out of a "next generation" part I suppose. Either that, or I'm getting to the point that I am no longer easily impressed. I'm just use to next gen mid-range cards that actually meet or BEAT the pre-existing high end.

It performs 50% better than last gen's midrange and is priced like a midrange card. And I'm sure the GTX460 was more than $200 before the price cuts; it's only now that it has reached better value simply because of the 68xx release. If anything, the precipitous price war that occurred over the past 2 days is nothing short of miraculous.

I don't get why everybody is insisting to use these stupid "open" coolers.

Almost all GTX 460 have been using different type of stupid coolers too. I was hoping they would find a better solution in this round. Why they keep insisting on duping hot air inside the case?

depends who buys. it might be stupid for normal joes. but for Ocers, beefy heatsink is heaven :clap:

On the contrary, an OCer needs a cool case, not Joe. If you OC you CPU and RAM, then you don't want hot air from GPU inside your case.

Why would a OCer want the hot air inside the case, when you can easily dump it outside. Specially on these "cool" GPUs, you don't need to sacrifice the case-temp for a good 24/7 OC on these GPUs.

Maybe because these "stupid coolers" are far more efficient at cooling than leafblowers?

If you pay attention, I'm not saying they are inefficient or bad coolers for GPU. They dump the hot air inside the case, and limits the OC on your CPU, RAM, and toast you NB, SB too.

I'm saying why they insist on dumping the hot air inside. Why can't can't they find a better design and keep using the same stupid one?

depends on what case you are talking about ;) open case is another thing.

if one is handy, it is possible to do own closed case for graphics cards. though cooling perfomance might suffer a bit..
-
ram? no problems. running corsair h50/70 inverted? (blowing air from inside) why not..

as I said, it is not for joes.

You don't get the point.
I've told you already, but you didn't get the point, apparently. Joe doesn't need a cool case. An OCer needs a cool case! What are you trying to imply by insisting on Joe?

If you are a OCer, you should know that you need a cool case.

If you have a good ventilated case( i mean with 3-4 12cm fans) you don't have any problems... Even if you don't have such a ventilated case, at stock volts, any GTX 460 doesn't warm anything. An doesn't limit any overclock on Cpu, let say 4ghz on an i5 750, or 4.4ghz on an i3. I suposed that if you have money for an i7 you have money for a good case too..
You just exagerate. :down:

Yeaaaaaah I think you're over reacting. I'd rather take an open air cooler if it leads to an inaudible acoustic footprint.

Are you trying to say, a hot case is the same as the cold case?
I don't know how much you know about OCing and cooling, maybe i need to explain.

Hot air from these stupid "open" coolers has sevral disadvantages:

1-Hot air gets sucked in by those big fans, and heats up you GPU too. So it's debatable if you get a cooler GPU.
2-You NB and SB are really closed by, and they get toasted.
3- Hot air will limit your OC on CPU, for sure, and would affect your RAM-OC too.

Better case-ventilation needs more fans, and it means more noise, and we should try to eliminate the source of heat for 24/7 first, and then add more fans.

funny you keep tell "cool" many times

firstly, you need "be cooled" down :rofl:

anybody knows OCer wants cold.. no needing to tell everyone

as I said it is NO problems for CLEVER Oc'ers

Coolio, not well cooled dude?

Who cares, pro's use watercooling anyways :p:

Edit: 24/7 not LN2 pro's ofc...
