We ordered some to pair with our GTX 1080 Ti models (and a few Vegas).  The plan is to have 6 Acorn 215+ paired with 6 GTX 1080 Ti on a ASUS Prime 370-A motherboard, using the ASUS Hyper x6 addon card for 4 Acorns (since that motherboard does support Bifurcation) and 2 Acorns on the M.2 slots on the motherboard itself.  If need be we can spread them out over more motherboards since we currently have more motherboards then GPUs on hand.
