Follow up, I did a little tinkering and slipped Sarah's gtx 1060 into Amber, then did two more test renders. Updating those performance numbers with the same test render-

Sarah : 2131 seconds ( 35.5 minutes) on GTX 1060 6GB

Amber : 7140 seconds (119.0 minutes) on GTX 1080 Ti

Amber rendering on 1060 only : 1893.41 seconds, 31 1/2 minutes

Amber rendering on both 1060 and 1080ti : 796.95 seconds, 13 1/4 minutes

I dont know what it is about the 1080ti on its own, but the 1060 seems to be fixing it. One thing to note is that using both cards did use double the ram, whether that is the ram on the cards, or system ram I dont know, but single card rendering used 1403 mb and using both went up to 2906mb

Yeah, my ram usage was around 2880mb with both cards running.
