SUPER... buy it,, just buy it.

UPDATE1: the mobo throttle the CPU above 4.6 GHz and without a fan on the NB+VRM heatsink u will never pass over 4.6 GHz and u will keep bouncing between 7 x multiplier and Ur OC x multiplier,, i don't recommend this mobo for extreme OC unless u know how to cool it.

Aside from RAM speed limitations, this board is exactly what I wanted. Also, the BIOS has a lot of options. Like a lot.

Has a few issues with USB 3.0 and sometime just altogether refuses to work on some devices. Windows 10 made the issue seems to disappear after upgrading from 8.1, possibly OS related? Loses a few good points with me for having that issues persist for months and no bios updates to fix it. Friend also with this board has the same issues but on Win 7.

A great motherboard! Supports SLI and it has 4 PCI-E slots in total! My misinformed review for this thought the front panel connectors problems was a hardware issue but it's actually a Windows 10 issue. Oh well.

After watching a video of jay on youtube using this mobo on his wife's pc, I was attached instantly. Its positive review and overall quality says it all. A very solid performing motherboard. BIOS is user friendly and easy to setup. My build had a been a success and looking neat because of this.

Awesome motherboard, great instructions, I did a light overclock but I still wouldn't take things far with this.

This review is for the revision 2.x board, which I unfortunately bought at the time. The reason being that the VRMs are sh- er, 'poo' for any amount of overclocking beyond the CPU's turbo clocks. It hasn't caught fire, so that's a plus. For the purposes of this build, this motherboard supports the necessary features for virtualization with hardware exposure, and even better is that I did not need to apply the 'PCI-E ACS override' patch to pass one each of graphics card and USB controller to separate virtual machines.

Bios is difficult and not my favorite. But otherwise with 3 pcie expansion slots and solid construction it is a solid mobo.
