I don't think I've ever run out of VRAM running 57X10 with 2GB, but I've never played SkyRim with the texture pack and 8X MSAA, nor have I played BF3 on Ultra settings. (don't have either game)
I can't speak for any other games as I have not tracked VRAM use.

For Skyrim with not too much more than the HD pack and the 1.5 texture packs I easily go over 1515MB vram use even after running the texture optimizer and this is not in eyefinity/surround this is on Ultra settings at 1920x1200 with 8xAF and 0xAA and a lighting add-on.

I even tried Eyefinity myself and could not get it to run favorably on a 5990 with 4GB total vram (2x2GB) on Ultra it would run for about 1-2 minutes then turn into a slideshow I'm guessing due to VRAM starvation in Eyefinity going across 3x 1920x1200 monitors so I'm not sure even 3GB would be sufficient.

Skyrim is probably the single most important game for those into RPG / games in this setting and many of us were waiting on NVidia to release something competitive, but since it does not have nearly enough VRAM for us, the 680 ended up being a disappointment.
