Pretty neat. Good part choices. Should give you 60fps/1080p most games on high settings. Here is another build you can look at similar price point. Equally powerful if not more.
Close to the same amount as what you had but better processor for around $30 more plus two sticks of ram so you can use dual channel which is much better then a single stick and you can always add more since you have a total of 4 slots on this mobo and since it's mostly for gaming you probably won't need any more ram at the moment and close future. Intel processor is still going to be better for gaming with higher single core clocks then AMD but you could do an AMD build and get a 1600 with 6 cores and 12threads for not much more then this prob $30 more.
