So I reached the point where my G4 powerbook just doesnt cut it anymore. Instead of buying another mac I figured I could build a hackintosh and get better results. Never built a PC before, but it looks straightforward enough from all guides I have read.

So I came up with this parts list, based in part on a post I saw on Lifehacker.

My questions are thus:
Is the power supply big enough? (850w)
I want to run dual 22" monitors. Do I need 2 video cards to do that, or will one be enough? I'd like to do some gaming on this. Should I go for one $300 card, or two $150 in SLI?
Can I dual boot 10.6 and Win7 on this? Do I need a 3rd HD just for the windows install?

Notice anything thats missing?

Thanks for the help!
