$600 Gaming PC Build!

I really need some help. I am currently a console gamer but I'm getting really sick of the graphics and the games that are all the same. So I've decided I want to build a gamming PC. I want to be able to play games like BF4, Bio shock etc.. Really I am open to any suggestions of good pc games. This budget of $600 does not include windows or any peripherals, just the cold hard hardware. If you could please help me out I would greatly appreciate it.   

$40 over but very fast. 6 Core CPU

Right on budget.

But you only get an Athlon quad core.

If i were you I'd grab the FX based build.

Thank You Guys
