$500 is very difficult but being able to go up to $700 really makes the difference between a normal everyday computer and a gaming computer. You can try Ibuypower.com or Cyberpower.com There you can build your own custom gaming pc to fit your price range. Or at Newegg.com you can buy a IBuypower.com or Cyberpower.com computer that has been prebuilt, at a discount price to help you save more money.
Ideally you would want something around these specs. 2.5 ghz intel processor - 2.7ghz amd processor 4-8 gb of ram Amd 7770 processor is a nice way to go, fast, cheap, and runs cool. Or its equivlent the NVIDIA Geforce GTX 550ti 2gb.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
