My friend got an offer on his gtx 480 for $100 and mainly due to its power and heat put out I was thinking that the 750ti FTW edition would be a good upgrade at least on the temps side, and maybe fps side not too sure. Would it be worth spending an extra $70 after selling the 480 to go to the 750 ti? Also should he go for the FTW or a different one that is normally $160?
