What does all this mean?
1: You can't believe everything you see on the internet.
2: Tweaking the OS to practically the bare minimum and restrictions on what programs use which cores yields results.
3: An i5 6400-6600k/1070-or-whatever-AMD-alternative is going to be the generic gaming PC until Volta, so I see no reason why a mobile i7/1070 isn't more or less equivalent.
4: I can't think of a reason why we are concerning ourselves about CPU power going into a low-overhead API future. Honestly, you'll probably have to lower settings due to the GPU over and over again long before you run into major issues on the CPU side.
