With all the Windows Mixed Reality stuff, HMDs are rapidly becoming standard commodity hardware. That's a good thing. I want to see resolution specs for the Valve headset. The upcoming HP one is the most interesting HMD to me so far with it's 2Kx2K resolution and presumably decent tracking.
I'm currently using a Samsung Odyssey and it was a nice step up from the Oculus Rift I had before, and the HP is a similar step up in resolution again over the Odyssey (+ ~50% pixel count).
Of course the trouble is GPUs. For most of what I do right now a 2080 just barely handles the Odyssey at a mostly constant 90FPS (depending on what I'm playing of course, I mostly do racing sims and some flight sims, and they vary in performance).
If I upgraded to the HP headset with it's bump in resolution over the Odyssey/Vive Pro, I'd probably need a new GPU too, but a 2080ti isn't 50% faster than a 2080... and that's the limit right now.
I get the feeling it's fundamental implementation (DirectX and drivers) that needs an overhaul. Having an SLI setup where one GPU draws each eye seems like a no-brainer, but turns out it isn't anything like that simple in practice.
