My previous setup was a q6600 @ 3.8 and a gtx 570 OC to 900mhz on the core but with a 600 watt psu. But you should be able to pull it off. If I hadn't needed to get a new setup due to circumstances beyond my control I would still be gaming on that. With an ssd dayu to day usage it feels about the same as my ivybridge xeon.

it's the same PSU right? same Serial number...
does those 30 watt make difference from seasonic to xfx i know that both are identical.
that EVGA 500B isn't a lower Tier PSU than the seasonic or xfx?
