I am looking to build a gaming pc (first build and not much experience). This is my build that I have made http://pcpartpicker.com/p/d72xbv. I am wondering if this could handle most games at decent settings and a high frame rate(games including battlefield 4, arma 2:dayz mod,rust, and possibly dayz standalone) if you see any room for improvement please tell me. Also please keep the price around $850. Thanks!
