I think that Ryzen should be better for VR. Many people report more consistent frames in gaming, with a Ryzen rig, and some frametime graphs that I've seen, seem to back up that assertion.
You might not get top FPS with Ryzen (although that's debatable the higher in res that you go, but you'll get more consistent frames. That's my understanding, anyway.
I dropped some coin the other night on a Ryzen R5 1600, and an ASRock B350 board. Seemed like a decent deal for $300. (No real savings over and above retail, just that the retail cost was not too bad.)
Newegg currently has a combo deal for a Fata1ity-branded board ($100) and an 1600X ($250) for $305, see Hot Deals for the thread.
