 From what I've gathered, it's mostly about using a stript to bind the 
GPUs you want to vfio-pci using the driver_override mecanism. Is that 
correct?

Really? From what I understood reading your IOMMU article, plus from the 
issues I had getting my own GPU to work on the CPU-based PCIe slot on my 
E3-1200, I thought having a PCIe root port grouped with a PCI device 
made the GPU unsuited for passthrougs. What reccomendations should I 
give here 
<https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Plugging_your_guest_GPU_in_an_unisolated_CPU-based_PCIe_slot>, 
then?
