@zsams, dont forget the Rex3, we both had crappy boards. Worst clocking x58 board of the 4 I tried for bclk, also the most expensive. I still cant make myself pull the trigger on another Asus board after that horrible experience, board still sits in the box.
The P67A UD5 has been a great board. It clocks higher than the UD7 I had been using, and scores great in 3D even at 8x sli or cf.
