Summary: I purchased two of these in January of 2013, and forgot to do a review back then. They have been working flawlessly, so I have no complaints. The BIOS setup program isn't my favorite, but it gets the job done. Quite happy with the motherboard.
Summary: This motherboard seems to be quite solid as I have use it for gaming etc. It overclocks nicely with my Intel 3770K processor. Although this processor get quite hot which is no fault of the motherboard itself. You can purchase other Intel processors that will work better with less heat and are just as efficient.
Summary: I have now been using this motherboard for six months and it has been perfect; I have had zero issues. The extras are very nice also. I have a Samsung SD hard drive for my main system drive and then use two 1TB SATA drives in a RAID 0 for a Data drive with the built in mSATA connector in front of it for better performance. The drive speeds scream. I also have a 8TB external hard drive connected to the Thunderbolt for video editing and it is extremely fast.
Summary: The drivers installed without error and is easy to update. It has thunderbolt which is nice since more of these devices are becoming available. USB 3 is nice and fast. Great board for the intel chip 3770k.

Summary: I bought this motherboard only because it was one of the few who had Thunderbolt support and I needed to use my 27'' Apple Thunderbolt Display; it works perfectly well, but if you happen to install a discrete video card it will default output video to that one until you install the Intel HD graphics drivers; also you will have to install the VirtuMVP suite (which this motherboard supports natively) to take advantage of external GPU power through thunderbolt.
