Glad i was broke during the holiz so i couldnt get the normal 3870's. 2 of these babies coming my way asap.

CF scales better but the cards aren't as powerful so they don't perform as well.

Expreview link shows a close result, no real winner. It does not test many titles either.

DriverHeaven have a more complete review with a vast selection of games.

Out of those games only 2 worked well in CF, COD4 and Crysis - both of these games return higher frame rates with sli.
GoW, Tiger Woods, Quake Wars, Oblivion, Lost Planet, World in Conflict, Dirt, HL2EP2 either didn't work or gave poor results.

This is why I am sceptical about any dual card. Mixed results.

I game @ 1920x1600 with AA/AF on so which ever card cranks out the highest frame rate/IQ across a broad spectrum of games with these settings will end up in my rig...

Only 2/4 weeks to wait now for both of these cards to be released, not long at all

If this is any indication of what to expect I can see why many are excited:

Yes and that was November 26th, 2007, with Catalyst 7.11. Cat 7.12 brought some performance boost.

[LyP0]

the cpu score of the gtx's is more than 2 times as much. But still the 3870x2 is faster. cause one sm2 its 35-40% more powerfull and in sm3 its more like a 85-90% wich is realy impressive.

If you pair this beast up with a york @ 4.5(wich is do-able on air) you'd have a nice 24/7 game rig.

[LordEC911]

Seems like the GTX would score roughly 7000 with a stock E6600...
Sorta find it amusing that there is 8gb of ram in that system, hopefully they have a reason for all of that.

[Zytek_Fan]

CPU is really holding back that 3870 X2

[realsmasher]

that hdr/sm3.0 difference is amazing

[kite7]

Can anyone do the GTX benchmark at the same CPU speed which is E6600 at 2560x1600?

would be awesome on a wolfdale e8500 @ 4.5 / 4.7

[nissangtr]

Here is the GTX results at 2560x1600









The SM2.0 and SM3.0 really tells the story

That Q6700 score of 4887 is kind of low. Did the cpu throttle during the test? My Q6700 cranks out over 5200 on 3DMark06 on default voltage at 3.4ghz.

[realsmasher]

using vista ?
using only 700mhz ram ?
using only 350fsb ?

300 cpu-points really aren't that much.

Anyone know if two of these will work on a p35 board with two x16 slots, like the mars for example?

It should work just fine.

[nr2134]

It should work just fine.

But he better overclock the crap out of that E8500.

[realsmasher]

for what ?
Gaming ?
you can't be serious.

[Damien]

i think he meant so the cpu won't bottleneck it.

i'll probably just grab one, it was more out of curiosity.

[Eastcoasthandle]

With 2 3870s in CF using a Q6600 you get 15800.





With the 3870x2 with a Q6600 you get 17414


using 2 dies on one PCB vs 2 video cards bridge together, both using windows vista. I suspect more will be gained when you go from 2 separate CPUs to dual core solution. The more efficient the design the more performance should be had. Hopefully when reviewed the X2 will show a boost over CF solution. However, you have to be mindful that these 2 benchmarks run the CPU at 3.0 and 3.3. Rumor has it that the RV670 was updated since it's release but there is no confirmation on that.

[STaRGaZeR]

That first Q6600 is overclocked to 3000Mhz, the second to 3330Mhz. Not a valid comparison.

[Unbornchild]

3dmark06, 1280x1024 default. Windows Vista.
Q6600 number 1=2997 Mhz; score = 4277
Q6600 number 2=3330 Mhz; score = 4764

Well ok, that's to be expected.

2 x 3870 in crossfire:
SM 2 = 6195
SM 3 = 7609

a single 3870X2:
SM 2 = 7035
SM 3 = 8134

Simply because the CPU is slightly oc'd you wouldn't get such boost in SM performance in crossfire.
This card performs better than 2 x 3870 in crossfire.

Wrong. You get HUGE perfomance boost in CF with every Mhz you put in your Q6600. In SM2.0 and SM3.0, the CPU score doesn't count here. I can make a comparison with 3000Mhz and 3330Mhz if you want

[mascaras]

With the 3870x2 with a Q6600 you get 17414

that's a substantial boost using 2 dies on one PCB vs 2 video cards bridge together, both using windows vista.

NO BOOST AT ALL

its samething as 2x HD3870 CF :



CF HD3870 + q6600 @ 3.4ghz + windows vista = 17200 marks >>> http://img527.imageshack.us/my.php?i...ssfire2ql4.jpg

"NO" what?! <----edit: oh you said no to Eastcoasthandle. edit2: ahh.. you edited.

Anyway, yes i checked my own history with single card:
Maximus Formula SE/E6750 non-oc, everything @ stock
HD 3870 out of the box, stock speed.
Windows XP SP2
Catalyst 7.12

E6750 @ 2.66 Ghz
HD 3870 @ 777/1126
3DMark06 (default 1280x1024): 10397.
SM2.0 score: 4474
HDR/SM3.0 score: 5072
CPU: 2405

....................................

E6750 @ 3.6 Ghz
HD 3870 @ 860/1301
3DMark06 (default 1280x1024): 12302
SM2.0 score: 5159
HDR/SM3.0 score: 5685
CPU score: 3229

EDIT: ahh.. i overclocked both, didn't check the 'default cpu + oc'd card' situation.
But you guys mean that the difference is huge in crossfire? Ok, i can't comment on that... just show me the figures, i believe you!

Oh btw: from the two reviews, the crossfire setup uses Cat 7.11, the other 7.12 (?) or a 8.1 beta(?)

[Eastcoasthandle]

That first Q6600 is overclocked to 3000Mhz, the second to 3330Mhz. Not a valid comparison.

It's valid base on the fact I haven't found anything remotely close as of yet. If you can find similar score be my guest and post it

Actually the boost is still there, even when your pic shows a higher OC. Which to me tells me something is not jiving with the CPU score at a higher OC.

with Cat 7.11 used and CPU its only +90mhz (200marks difference)


HD3870X2 + Q6600 @ 3333mhz + CaT ?? = 17400 marks (windws Vista)

2x HD3870 + Q6600 @ 3420mhz + CAT 7.11 = 17200 marks (windows vista)
