Because all boards perform within 0.5%, it's quite useless to check the benchmark results first. The only difference between the boards is power consumption and price. Let's check the usual power-consumption results first:
Here we have a new chart. All boards at 4GHz, except Elitegroup which runs "only" at 3.92GHz using Prime95. If you try to overclock above 3.8GHz make sure to limit C-States at C3, if the BIOS does not allow for this option, disabled C-States to ensure stable operation. You don't need to disable any other power-savings features, even when some manuals point out to do so.
