For a sec there I thought it said 6800GT. Honestly get the X800 if the only other alternative is a dated 6600. Not to mention barely any games take full advantage of SLI. If I were you I'd get a nice 7800GTX or a 6800 if you're a little short on cash.
why don't you get the 128mb 6800? most games don't even go past using 100mb of vram and by the time they do, your card won't be able to play them well anyway.
mmm I'll think about it... btw does the memory affect the games??? I mean, do games show better if u have higher memory?
PC memory that is Depends on preference I like geforce coz i got a 6600GT myself and its very good I wont vote coz then ill be biased in a way-lol But both cards are good just cant mke up mind
to an extent yes, but most games don't require that much. it's like going from 2gigs of ram to 4, you really won't notice the diference, but you may get a fraction of a percent higher performance. again though, by the time you need more vram, your card wouldn't be able to play the games well anyway.
