Assuming you want to play todays games of course. I am talking about including operating system, mouse, and keyboard. People say for the cost of a console (IE PS3 $200) is a rip off and for the same price you can build and equal or better computer.
I own a computer capable of high settigs on most games, but I was just wondering about this. The PS3 has depreciated quite a bit since it's release so lets put it at a more reasonable PS4 price point (450-600.)
Consoles have games specifically designed for their hardware and are sold at a loss, it's difficult to beat their price. PC gamers tend to play at higher resolutions and quality settings than you can on consoles as well.
If you're playing at 720P, you could just use an A10-5800K and no graphics card.
