If you're spending a good amount of money on components, you'd do well to spend a fair amount of cash on the thing that makes them all work.

$80-$120 should do the trick power supply wise for a setup like that. Units that would fit the bill are the Corsair VX450w, Corsair HX520w, Silverston ST50EF-Plus, Enermax Liberty ELT500w (although it is a bit outclassed at this point), Seasonic S12 or M12 between 450-600w, PC Power & Cooling Silencer 610w, and a few other units.

Other bang for the buck choices...

Thermaltake W0106RU ATX 12V 2.2 & EPS 12V 700Watt $169.99 ($124.99 after rebate)

Mushkin 550150 ATX12V 650Watt $124.99

PC Power & Cooling Silencer 610 EPS12V EPS12V 610Watt $118.99

OCZ GameXStream OCZ700GXSSLI ATX12V 700Watt $134.99 ($99.99 after rebate)

BFG Tech BFGR650PSU ATX 12v 2.0 / EPS 12V 650Watt $114.99 ($99.99 after rebate)

There are some others, but I'm feeling lazy. Any of these would suit your system's power requirements. Of the ones I listed, I think the OCZ is the best bargain...after the rebate... ;)

Q6600 + 8800 GT can even run on Shuttle's 400W PSU. although it has higher-than-avarage 12V rail amperage (30A)

but you should get at least 450W or 500W PSU when talking about standard desktop-ATX-PSUs. spend on quality brand, so there won't be any unpleasant surprises. they cost more, but they deliver what they promise.

for example any brand that these guys already have mentioned on this topic.
