You cannot. If you have VT-X and VT-d, you might be able to create a Windows HVM and pass through your GPU, but Qubes official support for this is close to nil, and success is very dependant on your specific setup. Some cards plainly won't work, some won't work with given CPU/Mobo combos, etc.

I made my GTX980 work on Arch, and tried on Qubes, but Qubes itself was too unstable for my daily driver, so I never got it complete.

That's too bad. Oh well.

Another approach is to run a minimal Arch on metal, and everything else in VMs. If your motherboard is compatible with GPU passthrough, the dGPU can now be passed among the VMs without hardware reboot. The GPU performance loss is minor, but I saw added latency variance when doing VR. I've seen several HN comments from folks happy with this approach.
