Here's my attempt at building you a cheapish gaming PC, using code EMCKJHE28 on the CPU for $13 off...
If you're spending that much on the CPU you really might as well move up to the i5 2500 if you're not planning on overclocking or the 2500K if you are planning on overclocking. It'll be a bit more but you could shave some money off the PSU as 650W is overkill for a mere GTX 460 768MB. Even a 400W PSU would be ample unless you're planning on going SLI down the road.
