ok for an intel setup this is what i chose. (i really recommend amd for a budget like that..)
Power supply ( will be plenty of power)

CPU (chose this because it was the cheapest ivy bridge which is the one that supports 1600 ram)

Mobo (cheap, supports parts, and has usb 3.0)

RAM (good company, and is clocked at what you want)

Case (not sure whether this will be on your website or not, but if you get a cheap mid tower atx case you'll be set)

GPU (comes with farcry 3, excerpt from newegg review "This card performs well. I'm running it in a pci-e 2.0 slot but i haven't seen the fps drop below 40. I play Mw3, hitman: absolution, skyrim, dirt 3, max payne 3, assassins creed 3, arkham city, Bf3, and gta iv all in 1440 x 900 and on max settings with the exception of tessellation and anti aliasing which are set to medium settings. Great card for the price."
So theres what i would suggest for an intel build, however i really would choose an amd route. For the price of the dual core intel, you can get a quad core amd. intel does excel in single threaded performance however..
