500$ won't get you much even at extreme bottom it will run
100$ for a good gaming mouse keyboard
60$ for a power supply
50$ case
40$ CPU cooler
100$ hard drive non ssd unless u go 128gb(ssd destroy reg hdd for any purpose)
100$ for a motherboard
100$ for a garbage amd processor
250$ for an intel core i7 probably 190$ for an i5
100$ for ram which should be no less than 8 if not 16 gb 1600mhz
150$ gpu I wouldn't go under the 660 and if possible go 670 or better. For the resolution you are going to run you don't need to much video ram.
No offense it's just not possible unless you are going to get a bundled amd set from new egg for 450$ round a bout then you still need to get the gpu and some other parts. O yeah you also would need a blu-ray/DVD / cd player or burner. Not to mention you need to buy the windows 8 software that will run 100$. Either way good luck
