I'm going to be using the ASRock P67 Pro3 in my new build, which I should be getting within 10 days or so. It's fully overclockable with all the right voltage settings but doesn't have all the extra bells and whistles and slots, which is crap I don't need anyway.
The Pro3 is $140, which is a $20 savings I can use for bigger-better things elsewhere in the system.
