so in BF 3, you are more comfortable with the SLOWER 6950 2gb just because it has more vram?
the gtx570 EASILY beats the 6970 never mind just the 6950 2gb at 1920x1200 with Ultra settings and 4x AA.

heck even at 2560 with Ultra settings and 4x AA, the gtx570 is again faster than the both the 6970 and 6950 2gb.

I can post benches that show the 6970 and 6950 being faster. There is no baseline for BF3 benchmarks. Every site is using something different.
Also, BF3 is primarily an online game once the campaign is over, and that is a whole other ballgame and is more demanding than anything in singleplayer with tons of enemies and effects on your screen.
None of those cards can run this game at ultra with 4xMSAA in multiplayer comfortably, in fact there is no single gpu card that can deliver a comfortable MP experience with 4xMSAA and ultra.
Here are results from the same review on High settings without 4xMSAA, settings that would be reasonable to use to expect a comfortable MP experience.
Here the 6970 is faster than the 570 and the 6950 is a little slower, also a good deal cheaper.
I would definitely opt for more VRAM, anyone who wants to run ultra settings should be avoiding 1GB cards.

Wrapping things up, the only aspect I feel that EVGA has left underdeveloped on an otherwise very strong card is VRAM. As a result of SLI 2Win is a $520 card with 1GB of effective VRAM. We’ve already seen 1GB of VRAM pose limitations in a couple of our tests, and going forward it’s only going to get worse. Case in point: Battlefield 3, which we’re currently looking at. In a technical presentation DICE has stated that the combined memory consumption at 1920x1080 for the gbuffer, Z-buffer, and MSAA resolve data is 158MB; and this is before other buffers let alone textures. As a $200 card meant for 1920 and lower resolution, 1GB of VRAM makes sense for the GTX 560 Ti. But as a $500 dual-GPU card meant for higher performance, higher quality, and higher resolutions, 1GB of effective VRAM is the biggest bottleneck going forward for the 2Win. Realistically EVGA is in a hard place since using higher density GDDR5 would drive up the price of the card and make it even more expensive than the GTX 580, but at the end of the day I think the 2Win needs 2GB of effective VRAM to spread its wings through 2012.
Granted he feels 1GB is fine for a $200 card with the expectations and settings you'd expect of it. But we're at the point with some games where the VRAM is what allows better settings.
Look at the hardwarecanucks results with the same card
Ultra no MSAA @ 1920x1200
Ultra 4xMSAA 1920x1200
Performance tanks by over 50% on the 1GB cards. Look at the 580 or 570, performance drops, but only about 20% compared to the huge over 50% performance hit on the 1GB cards. Even the 6970, which doesn't deal well with with the MSAA setting in BF3, only shows a 30% drop. 1GB is not enough anymore, the more VRAM you can get, the better.
