The question of what are you going to be doing with the system plays a major part in how we answer that. General usage you would be looking at something like the MSI H67MS-E43, Intel Desktop DH67CL or a ASRock H67M-GE are all nice bacis board that would work well with that processor. If you were looking for something more for gaming I would say something like the ASRock Z68 Extreme3 is a nice board at that price point or Asus P8Z68M-Pro is a better general use board.
