I mostly play World of Warcraft and do general home computing. When I am comparing CPU's, and other components for that matter, which benchmark tests should I pay the most attention to?
What exactly are you trying to do? I get the feeling you are going down the wrong path. Benchmarks should be used to test stability, not choose which CPU.
3dmark06. For cpu reviews this will vary depending on MB/Graphic cards and whatnot, but it's a good for how on average things will work as a gaming platform. FPS tests are even better, I prefer World in Conflict and FarCry test personally.
