I'm using a Supermicro X7DVL-E board, which has 1 PCI-e x8 and 1 PCI-e
x4 (in an x8 slot).

You probably could, but I'm not sure that would work correctly in a
non-server board.  I think any server board that has a x16 slot would be
fine since more servers aren't really designed for using high-end

Looking at Supermicro's site, it seems that pretty much all of the 5000V
and 5000P based motherboards have at least one x8 slot.  The 5000X based
boards have an x16 slot, but those are workstation boards which would
likely use that slot for a graphics card.

Look at Supermicro's site under Xeon 5300/5100/5000 motherboards.  You
should be able to find a board that would work just fine for you.
