Yes, but the 896mb VRAM doesnt help at all.

896? The GTX 295 has 1792mb VRAM. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130510&cm_re=295_gtx-_-14-130-510-_-Product

Hehe thats a common mistake m8, it has only 896mb of effective VRAM (that you can really use), the "other" 896mb can be only used as a mirror by the second GPU, the same happens in all SLI and Crossfire setups. :wink:

yep.. it really is two cards on one pcb with no vmem sharing..

Hmm.. didn't know that. So that means with even two 295's I'm only getting 896 VRAM? This also applies to 480s so they only have 1.5GB with 2 of them instead of 3GB?

Very interesting. Never heard of that before. I feel jipped! :P

Yes, thats it, with 2 x GTX 295 you have 896mb of VRAM, thats 600mb less than a SLI configuration of GTX 480. :wink:

Indeed, I'm sure the 480s are also faster than the 295s for other various reasons too and I'd love to get my hands on a pair, but truth be told, the 2nd 295 was also my most economical option to gain access to NV Surround (I picked up my 2nd 295 from a good friend for only 200 dollars, as he moved onto a 480 himself). It would have cost me at least twice that to move onto the 400 series for a pair of 460s, or three times that for some 470s, or 5 times that for two 480s.. In time, I suppose. But I'm probably stuck with these 295s for awhile. Going to go make a post on the NVidia forums to see if I can find anyone else experiencing these issues..

Edit:

Hmph. A poster over at the Nvidia forums pointed out that Quad SLI with the 295s isn't even supported currently, and according to the system requirements page I suppose he's right. Sort of reassuring, and not reassuring at the same time. Hopefully drivers will see some improvements for my setup in the future, once they are officially supported.

Crysis runs fine around 40 FPS at 5040x1050 DX10 all maxed + AA4x with tri-sli of GTX 480.

It doesn't on GTX460s. I dunno what the problem is, as everything else runs fine, but for some reason if I turn 1920x1200, 4xAA, 16xAF, Very High on... it loads, runs for a bit then crashes. Without 4xAA it's fine. 6064x1200, 0xAA, 16xAF, Medium runs great, though. Haven't tried it higher yet. I think with AA on it's running out of VRAM and dying as it reports in the developer debug display 1700MB VRAM usage? It breaks 1200MB at 1920x1200...

It doesn't on GTX460s. I dunno what the problem is

I think two GTX 460 dont have enought "cojones" for a game like Crysis on DX10 all maxed at ultra wide resolutions.

Not enough VRAM was the issue. More soon.
