Here are my PC specs:

OS: Windows 10 Pro 64-bit
Processor: Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz (4 CPUs), ~3.4GHz
RAM: 32gb DDR3
Graphics Card: 2x NVIDIA GeForce GTX 660 2GB (Superclocked) in SLI
Mobo: AsRock z77 Extreme 4

Now with those specs, my PS4 outperforms my PC by a noticeable amount. And the PS4 Pro will make that gap even bigger.
