Bad reviews aren't their problem now, it's that people won't pay an extra $400 for incrementally better performance and a missing-in-action feature set.
Interesting that FEs are working, I had heard that that configuration was problematic. Have you seen much thermal throttling with them butting up against each other? I was going to resign myself to one blower 1080Ti in slot 1 and then a 2080Ti in 2 and 4, but maybe I don't have to :-)
