what specs can run most games on medium without any lags?

my budget is around the 500$, 600$ if it includes OS and a Screen (i already have a mouse+keyboard)

ps, im not in the US nor in EU, so... just give me specs, i can get the comps myself

or if you can save up extra $300 and get yourself a nvidia gtx 660ti or amd 7950 and you can run most games at max settings with 60fps
