For our test, we tuned each system to the maximum clock frequency it'd support without sacrificing stability. We used a Freezer 13 air cooler from Arctic Cooling. For the sake of a fair comparison, we used DDR3-1600 memory for all systems. While faster RAM could have resulted in a percentage point gain here and there, it does not change the relative performance of overclocked CPUs that much.
