If you're building a PC with a "locked" Intel CPU, you really couldn't do much better. It doesn't support the unlock features of the Intel K series, but it's a very solid, stable motherboard with plenty of expansion. Onboard audio, ethernet, and video (with loads of different output options), along with USB 2.0 and 3.0 ports, mean you don't need much in the way of add-in cards. In fact, I only have a single video card add-in card because I like playing games. Intel's CPUs are great, and Gigabyte makes some really excellent motherboards for them. This is no exception.
It also doubles as being the very cheapest Gigabyte motherboard you can get for an Ivy Bridge-based Hackintosh computer, if you want to run Mountain Lion on your PC. It's the same features and onboard peripherals as the more expensive GA-B75M-U3H, though the board itself is not as large. It works great and everything is supported in OS X with Unibeast and Multibeast, just get a CPU with HD4000 graphics or a supported graphics card.
