The Mobo Looks great, but I'm not convinced of ASROCK's quality, read Newegg's reviews of the board before you buy.
2500K for sure. Buy something that overclocks if you are getting a P67 or Z68 board. If not a K processor get a baby board.

I'm running an ASUS P8P67 vanilla and it works great, but I'm kicking myself for not waiting for a Z68.
