Summary: I'm using this board with an Intel i5-2500K, and have had zero problems with it. Windows 7 Pro installation was uneventful, and I haven't had any bluescreen or reboot problems. Idle temps have been around 80F. My only wish is that all the USB ports were 3.0, rather than just two ports. This will obviously be the new standard.
Summary: I am extremely disappointed in this motherboard. The professional reviews for it are good, but they must test those before sending them to the reviewers. I have returned this board twice for the same reason. The first go around, I installed everything in my new HTPC and pressed power and then got into the bios. It recognized everything...cpu, both sticks of ram, three hard drives, the bluray drive, the video card, etc...no problems with that so I was a happy camper.
Summary: Have using it for around 1 month and so far everything goes smooth, haven't explored all features yet, but will do when need it. Simply perfet in combination with my other hardware. I combined this with an Corsair Cooling Hydro-Series All-in-One High-Performance Liquid CPU Cooler CWCH60 for my Core i5 2500k and it does NOT rest in the capacitors as some ppl might say.
Summary: After reading a ton of reviews I finally settled on this motherboard for my water cooled core i7 2600K rig. Overall this motherboard is performing just fine however occasionally there will be a problem during the initial power on where the system will power itself on and off repeatedly and the BIOS screen won't appear (even with the stock settings). Powering everything off and waiting for a few minutes has so far cured the problem. Cons: o Only 1 Ethernet port.
Summary: From a performance standpoint, this board is tops. It really is nice. From every other perspective, the standard Intel board is much better. Let's look at the bad things about this board: 1) Still uses a hybrid BIOS. Not a full UEFI implementation. 2) Only two 6gbps SATA ports. 3) 6 SATA ports but only 4 cables. HUH? 4) Only the CPU fan can be controlled by BIOS or software. Other fans run at 100% or 50%. You need a separate fan controller for this board.
Summary: I purchased this mobo after returning an Asus P8P67 LE. Dear god, what a difference. First, to let you in on the story, I learned the hard way that even with its slick UI and flashy heat sinks, the P67 LE doesn't let you regulate voltages manually in the BIOS. You are stuck with autovolting :/ Also, the two pcie x16 slots will changes lanes to x16 and x4 when running two gpu's off them.
Summary: Aside from the included software (a bit of which caused my computer to repeatedly blue screen [I didn't install anything aside from the ethernet driver after the second Windows installation attempt, and haven't had an issue since]), this is an excellent, essentially perfect motherboard to use as the foundation for a new Sandy Bridge system (I went with the 2500k).
