Looks like a pretty solid build. Yes, you will be able to play on Ultra setting on games such as BF4 with stable FPS. System will be pretty quiet but I'm not sure about your PSU if it will be loud or not. You will be able to do light overclock with your hyper evo 212. Light overclock as in maybe 3.8~4.0? If you go higher than that your cpu temperature will start to get risky.
