I'm looking at a PSU upgrade no matter what, so I would like some input from people who know these things. So far, a CX750W is looking good, and it's a Tier 3 on the EggXpert list, so they think it's all right. SR-71 Blackbird gave me a suggestion a while back, but the price rose too high after a while, which leads me to my next point: can we try to keep this under or at $100? I don't need 1K watts, just enough to power my new 770. Thanks, and happy building.
