I am thinking about building or buying a gaming pc for around 700-850 dollars (US). I would like it to run battlefield 4 at around 40-60 fps on high, probably on a 1600x900 resolution monitor. I just need the computer, as I will buy my peripherals and monitor some other time. I've been researching and to me it sounds like I would want at least an r9 270x or a gtx 660, and in order to spend more on the graphics card, I think I will need to buy an amd processor, (not sure if the fx 6300 will cut it). PLEASE HELP!!! INEXPERIENCED!
