For some reason... Far Cry 4, Assassins Creed Unity, The Crew, H1Z1, Call of Duty Ghosts, Advanced Warfare have all been running at about 30FPS sometimes peaking to 60 buut going back down, no matter what setting I put it on I stay around the same FPS, I have tried tweaking the settings and turning vSync off/on and just plain setting everything to low/windowed, and everything seems to stay at ~30-40 no matter what.

I used to have a AMD FX 6300 3.5Ghz and got better FPS than my current CPU

CPU Temp: 45-50C // 113-122F

CPU Usage: 70-80% Sometimes peaking to 90%

Things I have tried:

Try disabling in game HUDs like uplay, Origin In-game, Steam In-game, etc. Those things have messed up my games plenty of times. I'm sure you've checked the drivers for all of your components but I must mention it.
Also try disabling proprietary software for USB devices like mouse, keyboard, disk drives, and the like. You'll likely find the culprit in one of the above options.

Best of luck.
