Unfortunately, we do not see the same close results in the overclocked mode because all mainboards overclocked the processor differently. The following table sums up our overclocking results:

A 100 MHZ difference in resulting processor frequency produces about 2% performance difference. So, 6.2-6.3% performance difference between Asus Rampage IV Formula and MSI Big Bang-XPower II is quite normal, although a lot depends on the test application, of course. The difference is greater in Adobe Photoshop CS5 and 7-Zip 9.20, but there is hardly any performance difference in gaming applications, where not only CPU, but also the graphics card contribute to the overall performance.
