Those ASRock boards I listed have been know for good clockers as well. The gigabyte board I posted is the same one I use and It clocks VERY well for a 8+2 Phase board. If he is benching then yes, I would recommend a 200+$ board but for sb 4.4-4.6Ghz is its sweet spots and the boards listed should do that with no issues.
