I have this board, running my RAM at 2.2V. Apparently it will destroy ram at this voltage but meh corsair has a lifetime.
I built the system myself and all I can say is that damn northbridge heatsink/fan is huge and will cause many problems when deciding on after market CPU coolers. the layout is very restrictive on such things as that. I had to modify the brace for the Scythe Ninja tonight which required a hacksaw and a metal file. Other than that everything seems fine. I have no probs with my E6600 @ 3.2. I heard RAM is an issue, but I'm not really concerned about that right now. Besides, it looks killer and has 3 PCIe's.
Overclocking is EZ mode and EVGA has a great warranty. Theres not much you can lose going with this board, besides the RAM apparently - make sure to get that extended warranty.
