Hey. I am considering upgrading the video card in my PC. I have a 9600XT. I am considering an ATI X1600PRO 256MB or NVIDIA 6800XT 256MB. Games I play include FEAR, Quake 4, COD 2. I have a sempron 64 2800+ and 1.25GB of RAM. The price difference in cards doesn't matter. Does anyone have advice on which card to buy?
