I want to be able to run Guild Wars in max settings and also run CoD4 in any settings really. I was going to buy the XFX 8800 GTS 320 MB Extreme Edition as I thought this would be able to meet both my needs but i'm not sure whether my computer could handle this video card. Is there any way I can find out?
Here is some information, not sure if this will help in any way
