I just got COD 2 and when I got it installed I tunred the graphics up figuring my computer could handle it. But i got a really chopy FPS. first how do I check my FPS while playing? and now I am looking for a graphic card upgrade. I have a chaintech geforce 6600 256mb in a PCI express setup. I have a SLI ready mobo. now should I just sli in another card or look into a better single card?? note: I want to crank the graphics and get a good smooth play.
