I assume you're talking about this:

http://www23.tomshardware.com/cpu_2007.html

Tom's hardware have a bunch of different benchmarks so you can match it up to what you are primarily going to use your PC for. For us multiboxers, the gaming benchmarks would fit best, so choose either:
Prey, Quake IV, Serious Sam, Supreme Commander, Unreal Tournament or Warhammer.

The score listed is frames per second (FPS), and obviously faster is better!

Note - The Intel CPU's are listed in blue, AMD in green and the two your select are in red.

Hope this helps...
