I want a system to play league of legends and Battlefield 3 on, I already have a good psu and gpu, I just want a decent processor to go in alongside that gear. I mostly want to overclock for the sheer pleasure of overclocking, just as long as I get decent numbers for those games out at the other end I'll be happy. I have a vtx3d 6870x2 so I'm comfortable from that end.
When gaming the single most important part is the video card and that will determine the game performance more than a cpu will. The cpu just has to be a quad core for the video card to be able to do it's job better and while Intel cpus will do a better job at the gaming end of things you have to go up to an unlocked cpu to get the better overclocker experience. Most of the AMD cpus will overclock but you take a bit of a hit in gaming and I guess if you overclock the AMD cpu enough you can get back that bit of a hit.
