I think I'd be looking at an APU at this budget. An A8 5600K already comes with a decent IGP and can easily be crossfired with a 7770 for around $200. Then you'd still need a cheap CPU cooler like a Hyper 212, a PSU like a cheap 500W CM (got one I use for jumping water pumps for $40), and a case which really depends on aesthetics. That would make for a pretty powerful $300-$400 gaming rig....
Offtopic but holy crap... Im a big tron fan too haha
Here a quick peek at my current desktop
Oh and thanks for the advice on the APU and everything else. I'll take that into consideration.
Edit: I'm heading to bed as its getting late. So I will be looking at everything else in the morning right after I wake up. Thanks again everyone
