I put this together with the help of members from the PCPartPicker forum. However, I wanted to get the opinion of the TH crowd. Could I play games at 4K with this setup? Will it run too hot or make too much noise to be enjoyable? Will I get smooth framerates on the most graphics-intensive games? I didn't include case fans because the case I chose already includes two that add up to ~134 CFM airflow, and I figured that would be enough. PCPartPicker estimated the wattage at 1119 W, so I tried to play it safe by getting a PSU rated at well above that.
