nice, I have the same board and processor. Based on your video card selection, you are spending top dollar on this system. buy faster ram, either 800 or 1000 Mhz.

I suggest a large power supply, I bought a 650W. Especially if you plan to install another video card in the sli configuration in the future.

As soon as you are up and running, make sure you install the update to the bios for the NVida board.
