3 - 8800GTX will use about 350w of power at load. Your choice of the Corsair 850w is a very good one. You could OC the Q6600 and add a HD or 2 and still have plenty of headroom.

The Corsair TX850 is an excellent choice. Your power requirements are less than you think. A lot of people mistakenly think they need more power than they actually need. I see it all the time here.
