3770k with a z77 board would be the best bet maybe the msi mpower board it has some really nice features if it is in your price range with the 3770k

What to choose?

MSI Z77 MPower, Socket-1155
or
MSI Z77A-GD80, Socket-1155

Seems like the MPower can run more BUS clocks than the GD80. Will that mean overclocking on the GD80 wont work on RAM?
