If you go P67 buy either MSI/Gigabyte. The one i purchased was Asus, and for me it was 100% perfect and ran a stable 4.6Ghz no problem. However some people still had problems, most we ironed out with the B3 revision.
Personally i would wait a week or so and see what happens with the Z68 stuff, it appears asus/gigabyte have just soldered the different chipset into the P67 boards whereas MSI are giving it a good overhaul.
