Source : Best Gaming CPUs For The Money August 2010--Tomshardware.
If you donít have the time to research the benchmarks, or if you donít feel confident enough in your ability to pick the right processor for your next gaming machine, fear not. We at Tomís Hardware have come to your aid with a simple list of the best gaming CPUs offered for the money.
You can use this hierarchy to compare the pricing between two processors, to see which one is a better deal, and also to determine if an upgrade is worthwhile. I donít recommend upgrading your CPU unless the potential replacement is at least three tiers higher. Otherwise, the upgrade is somewhat parallel and you may not notice a worthwhile difference in game performance.
