Here we can see how overclocking can yield a significant boost in system wide performance.
I used one of these boards recently. well not the same board, but an asrock Z77 board and the fact they put in all those automatic overclocking features is better than anyone elses. I dont think ASUS do that do they? you are expected to have good knowledge of the hardware to get good boosts.
ASROCK are in many ways leading the path IMO.
