Depends on your components and if you can build it yourself.
My current PC cost 500 bucks and has roughly the same power a PS4 has. Just that I use DDR3.
So far I have yet to find a game I can't play in the best possible graphical setting and I saw nothing at E3 my PC couldn't handle. I also run windows 7 btw.
the difference here is that I can always upgrade my PC for cheap instead of needing a new console.
I am an avid console gamer. I have a PS3, a wii, Wii U and a 3ds. I had a 360 until it got the RROD as well. As somebody who never plays online or multiplayer and prefers single player this setup works for me. if a game doesn't come to ps3 or nintendo systems I get the PC version. sure, I miss out on exclusives for MS consoles but since I LOATHE shooters there is nothing for me to miss anyway
