I don't really see the point in doing all of that work to compare gaming CPUs, when 3 out of 4 games tested are heavily GPU dependent. The one CPU bound game he tested (Civ 5) indicated that all CPUs are not equal.
They should be testing simulations and strategy games if they want to make the CPU sweat. Obviously benching online games is problematic, but there are plenty of SP CPU bound games out there: off the top of my head, SC2 with a ton of units, Arma 2, and one game that nobody ever benchmarks, Mount and Blade: Warband. 500+ unit battles with horses will bring any CPU to its knees.
