Speaking of logic - why are you considering VR and 120hz a great investment if EVEN with that 30% higher single thread performance and top end gear, you STILL experience stutter?
Would it not be much more effective to lock at 90 fps, and scale a system on that, avoid stutter because you don't have that high a frame time variance altogether, AND reduce the total cost of the system so you can invest more towards GPU / future upgrades / whatever else in peripherals?
The only real logic here, is that high FPS/high refresh gaming AND VR simply aren't ready for market yet, because the performance level and optimization of the technology is far beyond the spec of the hardware it is used on. You're basically pointing that out yourself.
The fact still is, that the market for high refresh gaming is purely competitive of nature and VR and competitive don't mix at all, for now and the foreseeable future. The only failure in logic lies with you and your view of what is feasible, and what is possible with todays' tech.
The only real high refresh gaming that happens realistically is playing CS:GO and MOBAs at the lowest detail settings and at a high competitive level. Everything else is just a personal preference of which the vast majority of 'hardcore gamers' are just overinflated ego's like yourself that achieved nothing in life but a rank on some silly video game. You then apply that ego to everyone's buying decisions with regards to CPUs while the ONLY niche that the 7700K excels in, is high refresh gaming. For everyone else, Ryzen is the go-to CPU right now.
Get a life and some sense in your gut. Shit. Speaking of faith in humanity...
