What do you guys think of this build? Am I buying a PSU with just the right amount of 500W? I'm only really gonna play SC2 on max settings on 1440x990, so thats my top priority. It's my first time trying to build a custom PC, so I'm really open to any feedback, and I'm sure that I overlooked something...
If you find some good combos, you could upgrade that 5670 to a 5750 or the AII 630 to a PII 955, for "future-proofing."
EDIT: Oops, forgot a case. The Centurion is fine, but have a look at some others.
The case is the part that I would invest the most in, relatively. I don't mean you should spend the most on the case, but that you should spend time researching what cases you'll be happy with. Besides the monitor, it's what you'll look at every time you use your PC. It's also the part most likely to be reused in your next build. I would personally recommend a Lancool K62 or CM690 II, though both are in the $100 range.
