I apologize for not answering your question but your best bet is to buy a PS4 or an XB1 with that money. For $500 a PS4 and an XB1 will perform better than that same PC will for games. If you really want to buy a PC though I suggest saving that $500 until you get to at least $800. You can build a pretty good machine at that price but since you're averse to that you can still buy a decent one from some of the boutique dealers. Sorry if this is no help.
I already have an Xbox One and PS4.
