This board was just released but should be quite good, it natively supports 400fsb so overclocking should be a breeze. Also it has a PCI-E 2.0 slot for future cards.

And personally, I would go with an E7200 if you are just going to be using this computer for gaming. Quads are great for benchmarks and video encoding, but in terms of gaming they are not fully implemented yet...and when they are they will be even cheaper so you can just upgrade.
..and go for the PC Power & Cooling psu
One last thing, if this cooler is available before you place your order it's definitely worth the extra 2 dollars over the Xigmatek:
