Problem with switching the boot GPU (and with some other things)

I switched after reading an article on gamers nexus that confirmed that my 1060 would not have reduced performnace by the 8x PCIE slot

With a 1060 maybe but with a Vega64?
On the other hand, bandwidth on a VM seems to be limited anyway:

Increasing VFIO VGA Performance

Hi All, Last month I was spending considerable time pouring through the amdgpu sources in efforts to make it possible to reset the VEGA10 series of cards. While doing this I noted that the amdgpu driver checks to see if the GPU is connected via PCIe Gen3, and if so, it programs some registers in the GPU. This got me wondering if NVidia do the same…

But for linux gaming it would definitely mean a performance loss.
