I have a Phenom II 1090, and I've been very impressed with its performance. God knows I probably haven't actually used more than two cores, but it's a 3.4GHz processor per core, which is a nice speed. I kept wanting to go i5, but the AMD prices kept me coming back. I'm a sucker, I know. That said, if you go AMD/ATI it (seems) that the components work better together than when I mixed an AMD processor with GeForce graphics. Maybe the same goes for GF and Intel, but I doubt it.
Other than that, as posters above stated, don't go bargain brand PSU's. Get something decent. Nothing messes up a computer more than when a PSU goes bad. (Bought a coolmax "GREEN POWER" PSU. NEVER AGAIN.)
Also, I recommend Thermaltake cases. Lots of fan holes for lots of fans.
Thats the case I first looked at, I was set on it at the start
