This config would be the best bang for buck for your budget and interest (gaming)
I agree, those extra 40$ on cpu/mb together are worth it because OC'ing is so easy and the performance boost is big if done properly. But yeah, if he goes out of his way to mention that he doesn't want overlocking then I think you need to respect that.
By the only trusted guys in PSU reviewing (aside from 2 other sites..)
Coolermaster has a decent 600 watt unit here. The unit does pretty well for stability and efficiency, doesn't get very loud, and... what? It's a 750 watt unit?
Past Coolermaster units have done pretty well here in the lab, and I'm puzzled that this one has done so poorly. I hope that next time, if there is a next time, we'll have something worth getting excited about.
The review tells us the PSU is actually a 600W unit with a 750W label.. thats what cheap PSU's give.. less than they say!
Buy any of these power supplies (to power a GTX 570, and a single one).
get a... 500W-650W psu from... Antec (EXCEPT NOT BASIQ series from antec), Corsair (anything except for CX/VX), XFX (any), seasonic (This ones expensive and not better).
750W of any psu from antec/corsair/seasonic/xfx if you wanna sli (recommend 850w tbh)..
