Has anyone tried using a pci-e hub in slot 2 (x16) and using 8 GPU?  All I've seen on this thread is pci-e hub on slot 6 (x1).  I don't think it would matter because they're all connected on x1 lane, but who knows??  I want to run 8 not 7 but need some ppl out there to make sure

also, which mobo do you all have:
h81 pro btc +, or
h81 pro btc + r2.0
