Looks excellent. I also just built a rig with the same cpu and socket. (see sig)
I would suggest the ASUS M2N-SLI Deluxe motherboard over that one.
It's about $20 cheaper and better
I have it and it's awesome. It has HD audio which sounds as good as a highend
Only thing is I would suggest probabley a 500 or 600Watt psu instead.
Get a OCZ GameXStream 600Watt. I have the 700watt version
Everything else looks superb.
Good luck and enjoy
