Im no expert but you could play those games at ultra 60FPS 1080p for like 700.
i5 4460 is good
You could probs go less on motherboard as it's an overclocking one
you could change GPU to a GTX970 which will easily do what you want
Trust me you can't (for $700), especially DayZ, I only chose the motherboard because it can support crossfire, that also goes for the power supply, I prefer r9 390 over gtx 970 anyday, since it has 8gb of VRAM, plus it proves to be a bit better with benchmarks and is better performing especially under dx 12... So obviously r9 390X will be much better, it's basically a gtx 980..
