So my setup currently is listed, but I was thinking of getting another 5850 for a Crossfire setup. I'm pretty certain my Corsair PSU will be able to handle it, but just wanted to know what everyone else thought. Thanks in advance.

I think your PSU would be okay. I'm running 2 5870's on a Corsair TX850W. Before I bought the second one I did a check with this PSU calculator using some more stressful parameters than I have (particularly capacitor age, system load, and TDP). I think it spit out 805W as a recommendation. When I got it installed and tested...etc I plugged up my Kill A Watt and found that my max total power draw running Heaven Benchmark (max settings) & Prime 95 (large FFT) was 678W.

Not sure if I want to go for the Xfire setup now, or get a new monitor since mine is pretty awful (23' Dell that only does 60hz @ 1680x1050 and has like an 8ms response time).
