TX950 is way overkill, but if you can afford it, go for it. It will allow for CFX or even triple CFX in the future. The Thermaltake Frio OCK 0575 is a beast! Very loud though, and im not a noise snob. I dont mind it, but some would. If you dont plan on CFX, you can get an HX650W, or an Antec 750W EarthWatt psu for your system, and save some money. Best of luck!
