really good power supply for opteron 165

[madworld]

Please help me to choose really good Power Supply to my opteron 165 with two asus7800gt. At least 500W and dual 12V.
What is the best brand name for PS?

OCZ Modstream 520W
it hasn't got dual 12V rails, but it is extremely stable. output power will hardly budge, so it'll keep your computer stable.

OCZ Powerstream Series all the way. I haven no personal experience with the modstream but i chose the powerstream on recommendations from others here. The Powerstream is pretty good to me.
