What's a reliable brand/model for PSU's then? I'm completely lost there.

It's been rewarding trying to find cheap deals, but I don't think I can compromise too much on my budget. I'll probably go with the Athlon processor, I can always set up a new rig in a few months and use this one for surfing.

Oh, and I was wondering about the i5 vs Phenom 2 x6 - which one is likely to dish out more ppd?
