I'm in same boat. I love what I'm reading about the Reverb. Higher resolution is what I want. I'm not even just talking about in cockpit, I'm talking about outside the cockpit.
I am running 9700k OC to 5.0 and a 1080ti. I get 80 fps with Odyssey at 200% and Rift S similar. I returned the Rift S though as the clarity outside the cockpit is just not that great to me.
My biggest concern is IPD, I have 58 ( I think Wags said he was 59).
So the options are Pimax 5K+ where I can adjust the IPD and get the better FOV - or - HP Reverb with the better resolution.
One factor with Pimax 5k though is I'm going to not only need to buy a VR unit but I'll need to get a sensor and controllers, so that is extra $$ . (they have a bad model imo, everyone else includes this ???).
Leaning toward the Reverb - better cost, better resolution... and hoping the IPD isn't a big factor...
