Consider looking at the Asus P6X58D-E 4 a mobo. Great performer, with usb and sata 3. With a bundle deal like that, I would consider it myself though.
Switch the psu to a modular one, you'll thank yourself 4 doing that later on.
If you care to, switch your DVD to BR. They've come down in price considerably.
Keep an eye on the BST threads. You may be able to get a
pr of 460s or even a 480 for close to the same $.
Overall it looks like a solid build. Prices will come down with the launch of the new line, so if you wait a little longer the bang for the buck will be better.
If the new cpus are that much better and not too expensive, it may be a better choice as well.
What's a cpl of months if you're ok 4 now.
