Ok so at the moment I have my GPU: "XFX Radeon HD 7870" which I upgraded a few weeks ago, I've realesed on most games my GPU isn't giving me much fps, on every game, ultra or low it gives me the same low frame-rate as I think it's my CPU (Intel core i2 quad 2.5ghz) restricting a large amount of my FPS, any advice on what new CPU I should buy, I hear radeon's with radeon's work better.
