Windows reinstall is very likely to be a waste of time if you're trying to fix true limiting on your hardware. Why not run a live Linux distro and run some stress testing? This will take 15 minutes, including the usb creation, and net you the same results without causing more work with the OS reinstall.
The good news is that you've probably always been dealing with power limiting, but something else is impacting your performance. You didn't go looking under the hood before the performance impact. I'd really not focus on this.
Check to make sure you didn't enable "whisper" mode in GeForce experience and you aren't running in any type of power save. You can also set your max cpu performance in power options to 99% to artificially disable the processor's turbo boost, if you think there's some other kind of power/temperature limit being imposed. You'll notice you're running pretty close to the stock clock on the CPU, which could give you headroom elsewhere.
Or... there are 14 other factors that would need investigating.
