@ fullzero  

here is a really detailed build of the nvoc0017  with 2 nvidia 1070's on a

GIGABYTE GA-Z270P-D3 LGA1151 Intel Z270 2-Way Crossfire ATX DDR4 Motherboard.

to all this is a solid board  really good

I tested stable up to 5 amd rx 480's  on win 10 and smos
I tested stable up to 4 1080 ti's on win 10 and win 7  tested up to 3 on nvoc

I am sure it will do 5  on all of the above well maybe not win 7.  I just did not test that high on all os's
