okay I'm finally going to be able to upgrade my CPU (and that means MB and ram too and finally saying goodbye to ddr3) so I can enjoy more and more recent VR games, but I'm actually unsure of where to go now

looks like AMD finally decided to move their asses and are back in the race now?
but then intel still gets better perf overall it seems, just at a slight up in price?
what about VR wise? should I go for the poos?

I'm guessing the most I'll play will be vivecraft and I'd most likely enjoy playing gta5 in vr too, so I plan on getting something pretty beefy, but at the same time i'm not sure if I should really go for the i9 meme either, do vr games even use more than a few cores still? 
should I stick to an i7 with 8-16 at most? or should I fall for the i9s? 
should I maybe wait for this year's intels'?
