Using the Gigabyte UD5H with an i5 3570K and I love it so far. I've always been an ASUS user but the Gigabyte board had features and components of more expensive boards so it was a great value to me. When you pick this up you can feel the weight, it's has a nice feel to it, the black PCB is very nice. Bios is very easy to use as well.
So far I have my i5 OCed to 4.5GHz @ 1.130v in the bios. Currently doing the usual stress tests and running smoothly.
Just wanted to give the UD5H a
and thanks to this thread, it was very influential in helping me pick a motherboard.
