Can you confirm this? 
Does reverting to older Mesa release "fix" the new issues?
Or/and reverting to older kernel.

Slow deterioration of the situation is consistent with hardware problems. That
might not be so bad, because it means it could be fixed relatively easy.

BTW are you using suspend to RAM? My card had worse symptoms after resume, even
if it has been suspended for seconds. Suspend still provides +5V on PCIE, so
the card might still be partially powered, but not cooled.

This reminds me of something we haven't tested - ASPM.
Try kernel parameter "pcie_aspm=off"

Disabling it might lead to more power consumption by the card, even when idle.
But it might improve stability.
