zero config about vfio/pcistub on the grub/modprobe.d/modules-load/etc, except:
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on"
taked from:
http://www.altechnative.net/2015/04/05/virtually-gaming-part-2-evolution-consolidation-and-move-to-kvm/
that configuration have a identical GPU like you
i hope helps you
greetings
