Even then, a 9600 GSO won't last you very long in the game world, and it might run CoD4 fine at a decent resolution, but not world at war at anything that's remotely decent. Unless you play at 1280x800 or something.
Even then, why not spend more and get something that'll last you alot longer at that resolution? Also about the card being a "throw in" lmao. Steam just had world at war for 25, and 4 can be found cheap too.
