It turns out it's the processor that does not support VT-d. So Asrock is 
off the hook.

I found The Passthrough Post website which has a list of compatible 
hardware. I think I'll do some tests here with a Gigabyte RX 550 D5 and 
then we can pick something from that range.

On the Nvidia side I don't know if picking a Quadro instead of a 
consumer graphics card would have an impact on the Wine tests.

Otherwise it seems the code 43 error and MSI interrupt issues are 
reasonably well understood and can reliably be worked around these days.
