What's a good 600-900 dollar pc?

   Alright, I have always loved gaming but all I have is an xbox 360 and this crappy office pc that can't even run tf2 smoothly on low graphics. I am looking to build a 600-900 dollar gaming pc that can run games such as BATTLEFIELD 4 on high settings nice and smoothly. I am a noob at this stuff btw, I dont know what most the crap is >.<! Please help in the comments :D! HEEELP MEEE!

    Crap I try to look at:

      Amazon.com

      Tigerdirect.com

      Newegg.com

673 US dollars: http://pcpartpicker.com/p/32jyW This will run BF4 at high 1080p no problem.

946 US dollars: http://pcpartpicker.com/p/32vOw This can run Ultra at 1440p or 1080p with anti aliasing.

I like The Lone Wanderer's 946 USD build except for a fews things. You should get a case capable of high air flow, that $45 fractal case does not have very good air flow. His other recommendation, A $45 NZXT Source 210 does have good air flow. Be sure to get an aftermarket heatsink, like the Cooler Master Hyper 212, and an operating system. I suggest a flavor of windows 8.1.

Here is my build http://pcpartpicker.com/p/32DkJ for $80 more you could get a GTX 770.
