I'm not 100% sure, but those games probably wont be the most demanding games. You probably dont need to spend $1000 if thats all you're playing.
you could always get a middle of the line card now and have the option of crossfire/sli. i hear those gtx 460s are a pretty good deal.
What resolution is he going to be playing at?
Sandy Bridge comes out the second week of jan, no? This computer was meant as a Christmas gift but if waiting will make that big of a difference I suppose I could.
The point of waiting for Sandy Bridge is to utilize those processors? Or drive down the price of current i5/i7, leaving more money to be spent on a gpu which supposedly will drop in the coming days due to AMD's new release?
