Actually I bought the RX460 because first I wanted to use my old HD7850, but then my pc didnt even want to boot (linux, didnt try windows). It just hanged seconds after grub loading with a lot of those PCIe Bus Error's. Then I tried a couple Nvidia NVS295's I had but I couldnt get them to work properly (driver issues which caused mismatching colours). Probably there is just something wrong with that MSI RX480, as it gave those PCI-E Bus Error's also when it was the only GPU in my system (while I was waiting for the RX460). But then again, it's strange that the rom could be extracted correctly with GPU-Z under Windows. I did a Unique Heaven test and the results where not bad, ~1350 points and 53fps. But during some scenes it seemed the camera movement slowed down and then sped up significantly a couple of times. It didnt look like that was intentionaly but that said there was no drop in fps. Will do some more tests tomorrow as I am also not yet really happy with the sound quality (too much noise sometimes). Yes, I extracted the uefi bios from edk2.git-ovmf-x64-0-20170120.b2426.gaa961de.noarch.rpm. See xml below.

Unfortunately it didnt work then yet, as my dmesg was flooded with the following message: vfio-pci 0000:01:00.0: BAR 0: can't reserve [mem 0xc0000000-0xcfffffff 64bit pref] This was caused due grub loading vesafb for the RX480 as the graphical terminal was enabled. So in /etc/default/grub I had to add GRUB_GFXPAYLOAD_LINUX="text" and disable 'GRUB_GFXMODE' (not sure about the last one as maybe thats implicit but it doesnt hurt either). Unfortunately that does mean I cant use ddccontrol it seems, as that complains about missing a framebuffer driver. Therefore I've also asked Asus whether they plan to support choosing the primary vga slot like Gigabyte does and they said 'they will discuss this internally'. My Asus support agent actually had never heard of vfio before and repeatedly said that Asus only supports multiple GPU's when using SLI/Crossfire. So maybe if more people would contact their local Asus support agent and request this feature they are more willing to look at it? Who takes the hint? ;) I had to install the driver twice as the first time the install failed, but at the moment the GPU appears to be working correctly.
