another performance thread

[cato]

is a card with 1.5-2GB of vram really requires to play this game with good performance?

is now the time to buy a card thats gonna last me for a few years or would i be better waiting until the 2GB+ cards come down in price a bit?
the only 2 games that give me performance issues are this and arma2, both which i read are more cpu hungry than gpu which is why i upgraded my cpu.

if i upgrade my gpu im also gonna have to get a new psu as it only pumps out 500 watts.
