FPS Problems in Multitude of Games

[peppyrook]

I just recently put together a PC that should be more than reasonable for most games I currently play, yet I'm getting unstable FPS rates through almost all my games. Keep in mind nothing has pretty much been done to the computer, aside from me upping the clocks for the GPU and memory by a ~170 and ~600 respectively. Even at their default clocks, the same problem stated below happened.

For an example, Nvidia's GeForce Experience keeps suggesting I at least put all the settings on High while also setting render distance to 6000, yet that barely yields me a FPS of 60 nonetheless a steady 60 nor 55; also the game feels minimally jerky (like a frame is skipped). Also, when I get into huge battles with multiple particle effects going off I drop down to about 40 FPS.

Air flow is great, GPU is clocked at 1420 while the memory is at 7600.

Listed below are all my parts via the dxdiag.

Some games are just so optimized that even high end machines have trouble running them(I'm looking at you DayZ)

Your GTX 970 needs 28 amperes on the 12 volt line, but your psu only gives 25 amperes.
