Micro center combo: Just under $300 for CPU & Asrock z77 (had to pick it up at the store for the deal)
1. I went with PC Power and Cooling Mk III, 600 Watt psu. Silent and thrifty w/ reabate. Modular too. A little less power than I was thinking / wanting but,
2. After much thought, I decided NOT to SLI / Crossfire. Instead, I'll OC CPU & GPU until I buy my next updated GPU (1-2 years). Currently running a reused 6850 and it's doing everything I need it to
3. SSD. Pls consider an SSD. I have an Intel 330, 180 GB. Cruicial M4 & Samsung 830 are both great as well. Once you use and SSD, you will not ever use an HDD for your OS. It's just that simple. i would not go below 120 GB.
4. Corsair & Seasonic are great PSU brands as well
