I am upgrading my graphics card to a 8600GT 256MB, I currently have a Intel Pentium 4 520 CPU with Prescott core, I was wondering if I would be able to get decent FPS (50+) on newer games such as Battle Field 2/Counter-Strike: Source on high settings without having to upgrade my CPU... any thoughts? Btw, is the 8600GT really worth it, or should I just purchase a 7600?
