[GUI Boot and VM GPU Passthrough]

Get a Gigabyte motherboard. It would give you flexibility in GPU placement i.e. you don't have to place the P400 on the 1st PCIe slot.

Gigabyte BIOS allows you to pick any PCIe x16 slot to boot with (it's called "Initial Display Output").

Thanks for the tip! I was initially gonna go for asus cause they're the only one with a white-ish motherboard with an x570 chipset. I guess it's gonna look way better if I could put the 2070 on top of the quadro card.

Once a GPU is passed through to a VM, it is exclusively by the VM. While it's possible to pass it to another VM if the current VM using it is shutdown, it is NOT possible to return it back to Unraid to use for the GUI on the server.

This is the exact answer that I was looking for! Thank you! I'm planning to build an Unraid server dedeicated for gaming, a plex server and a file server and maybe a Mac VM too. I'm getting a Ryzen 9 3900x, RTX 2010 for GPU pass through for the windows VM and a quadro P400 for transcoding (and unraid GUI if ever I need it so the RTX will be used solely for gaming).

What if I'm running a ryzen cpu with no integrated graphics? Can I still access the GUI and have a gpu passthrough at the same time?
