Summary: What can I say? It's an INTEL motherboard made for SLI. I know a few people have bad-mouthed this particular product, BUT, IT WORKS. After trying to save $90 by purchasing an EXTREME6 board, and 9 or so days of pure frustration with it (ASRocks tech support people are very nice but couldn't help me), I went to Orlando and purchased one of these boards. It was up and running in no time at all (grandkids love it for their games).
Summary: An Excellent Board. Very capable and fun to use. Suggest upgrade bios all the way to version 66. Do it incrementally, starting with version 45 and work your way to version 66. You can skip a few along the way, but be sure to wind up with version 66.
Summary: I've built 5 Intel systems and this is the first one that has let me down. Setup went well til I discovered a memory slot was bad, so Intel sent me another motherboard after significant troubleshooting on my end. Then, I get the 2nd motherboard and I get a bios error 12 on startup. I googled that error and it seems that it is a common issue, with this motherboard.
Summary: The motherboard has been great, there have been some issues with the onboard NIC's that are probably mainly my fault, but other than that, I've never had it fail to boot up to Bios to at least allow me to recover my operating system. Easy, Graphical Bios setup with many, many options. Couple it with the proper processor, and you'll have a great time.
Summary: It works. It would be nice if the onchip graphics had a DVI header along with the HDMI. I would have preferred fewer SATAII and more SATAIII. Almost too many USB ports to connect. One of these days someone is going to have to come out with a 12 port USB front panel for all the internal headers. But why, since USB 3.0 is backwards compatible, are there *any* USB 2.0 ports?
Summary: I am not going to spend a lot of time writing a review on this board, because the only difference in this board and the Intel Extreme DZ77GA-70K, is this board has a 10GPS Thunderbolt Controller, and costs more. I will say this though, this board is their best socket LGA 1155 board, and it is very stable, and runs Windows 8 Pro very well once you get the settings right. Both boards use the same drivers, and same bios versions. Word of advice.
