<< I saw someone in General Hareware upstairs say 32MB is not sufficient anymore, 64MB is standard, and 128MB is even better. Is that true? >>
Nah, that's not true, the video memory factory actually weighs pretty lightly on overall video performance. I have a 32MB card right now (TNT2 M64) and i'm planning on upgrading to this GF2 w/ the same amount of memory because 32mb is still sufficient for pretty much all games.
I guess you could say 32MB is good, 64MB (such as on the high end TI500's) is great, and 128MB (on some of the new TI200's) is overkill
But that's just my opinion
