What CPU do you recommend and does it effect a lot of fps even when I play with just one card which is the amd 7970 oc edition, and thank you for letting me know before I blow my money for something that wasn't going to boost a lot of my performance can you tell me a CPU that you recommend something that 100 to 200$ but my CPU that I have right now is it effecting my fps I'm getting when I play video games or it would just effect it if I would crossfire?
