I need a 800$ max gaming pc for playing bf4 at 1080p on ultra preset over 60fps. I would prefer that the entire system would be under as little voltage as possible, I don't want to be paying a lot of money for my utility bills. I would also prefer if the cpu would be intel and the gpu would be nvidia because of their lower voltages compared to an amd processor and gpu. I would also prefer the case to have a window and has good airflow for just gaming, nothing serious. A case with great cable management would be appreciated, and mid-tower should be enough. Please include the windows os in the final pricing, i prefer windows 8.1 64-bit. If you can fit in an ssd and 8gb of ram instead of 4 would also be appreciated, I know i'm asking for a lot but I would be really happy if someone can help me.
