I don't know what PSU you can get, I can just tell you: don't cheap out on it. Get a good 80+ silver 650-750 W PSU (modular or nonmodular), and dump the Win7 home premium. I have a 750W silverstone 80+ silver full modular PSU and I never had any problems with it, although  I don't live in america, so it cost me about the equavalent of 200$. So yeah...

Don't get OCZ power supplies. They have bad coil whine issues.

Get this PSU instead:

Everything else looks prettys solid to me, but I would definitely throw an SSD in there too. Just get a cheap 64GB SSD and run it as a cache for your hard drive. That will speed up your computer quite a bit.

wouldnt it be better to go for an ivy bridge I5..? I know they run warmer, but they still have a better performance I think.

in general, you should stay away from OCZ right now..

Sandy Bridge will overclock higher most of the time and you'll get more performance out of it as a result. Ivy will give you PCI-E 3.0, but that's not really necessary right now.

OCZ makes good SSDs. I have a Vertex 2 in my laptop, and it works great.

Thanks for the help
