Before people start bragging on what they have, i would say check the requirements on the Ca site if this is for combat arms. If you are talking over all, i would say not really. videos cards go out of date very quickly. Nvidia Geforce is in the 9000 series in think, and i use 7600 gt on my desktop.
7600gt worked great on win xp for even cod 6 and i think your might be cod 4, cod waw standard.
