Curious about VR Dev - specs to target PSVR?

Hi Everyone,
I'm curious about VR dev and my computer is end of life. Time for a new one - my goal is eventually develop for PSVR. I'm not a registered PlayStation Dev, yet - but rather than waste Sony's time with nothing interesting, what kind of specs should I put into my new machine to "simulate" a PS4 with PSVR using say an Occulus Rift?

My plan was to experiment with my ideas on this new machine, maybe even produce a "draft" and then when I'm ready, register as a dev and move over to the dev kit with a clear understanding of the limitations of the platform.
