8800GTX or 2*8800GT in SLi i mean when hi end gaming, people often dont play at there native resolution. instead of doing that people prefer to lower the res a bit and playing the other settings higher. so in the end, playing at hi res in games like Crysis while playing at all hi settings, just makes it lag, so naturally, most lower the res to a point where all the extra V ram isnt really needed. thus a GTX or 640MB GTS isnt truly needed for this cuz the V ram wont be all used. plus, i was also told 512MB of V ram was only beneficial when gaming at resolutions 1600x1200 or more. so if that's true, a bit higher res may not be too much of a difference.
