Yes although I don't know what the processor supports on doorbot my i7
laptop does support VTd which allows me to pass through PCI busses in
hardware to VMs I use this function with my work, My home machine also
supports this, but I had serious trouble getting to to work with xen,
with all kinds of hilarity.

Agree and playing in a pi as Andrea suggests, is a good idea, because
what would be played with that can't be done on one.
