To be honest you would be better off spending a little more and getting the 955 black edition and an AM3 board. It would future-proof (kind of) your computer and also allow you to get the maximum power out of your video card.
*Overclocking your cpu is ESSENTIAL to unleashing the true power of these new high end video cards. Anything below 3.0 ghz will simply bottleneck the card, the more you overclock your cpu, the higher response you will see from your video card. The 955 Black Edition is perfect for this. Plus it's cheap compared to its sister intel processors.
