We tested all motherboards in combination with an Intel Core i7 3770K processor, 4 GB (2x 2GB) Corsair Dominator DDR3-1600 CL8 memory, an OCZ Vertex 4 128GB SSD, a Cooler Master Real Power M850 power supply and Windows 7 x64.
The charts below have the results from our benchmarks. The scores are pretty close together. The variance is no more than a few percent, and that's mainly due to the differences in bClk and the inaccuracy of benchmarks. Therefore the honest conclusion is that performance is not what you should look at when you are deciding which motherboard to buy. The ASUS board scores a little below-average, but it's negligible.
