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: 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: 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).
