Welp, its the cable. I couldnt stand waiting for a new cable to find out, so I pulled the case apart, mounted the rad at an angle to make clearance for the GPU, mounted GPU straight to the board, set PCIe 5 and everything works.
AC and DCS run super smooth. Fans don't even begin to spin up faster with either of them. Going to fire up PC3 and Dirt 2.0 tonight since they are VR resource heavy and see if I can get it to sweat a little, but I doubt it will. I think Horizons 5 is the most graphics hungry game I have, but that doesnt do VR.
New cable will be here Monday, then I'll go back to vertical GPU. Its a 4.0 cable, but shouldnt see much of a dropin performance, if anything even noticable.
