Qubes GPUVM questions

From reading current info, the nature of Qubes doesn’t allow to harness the full potential of high end GPUs without compromising security. I do have some Browser applications that bring any gpu (Intel, nvidia, amd) i tried to their knees with QubesOS.

My questions about guiVM

  1. i do need two GPUs one to boot up the host and one to pass over to gpuAppVM?
  2. possible to do this with just one GPU without blind password typing?
  3. installing manufacturers GPU drivers in the gpuVM template?
  4. gpuAppVM never has internet access?
  5. what the current status?
  6. How easy can you revert back from failed Boot aka Blind/Dark screen?
