i have a Mac Pro Mid 2010 (10.13.6 (17G5019)/2 x 3,46 GHz 6-Core Intel Xeon/128 GB 1333 MHz DDR3/NVIDIA GeForce GTX 980 Ti 6143 MB) and experience terribly annoying crashes (mostly suddenly logging out but also kernel panics) for a year or so. I work mostly in After Effects. I don't know if the kernel panics and Logouts refer to each other, but i guess so. So i hereby post a recent Kernel Panic crash report. Any help is so much appreciated! Thanks in advance!:

Edit: Thanks so far already! You gave me several very useful hints!
So, i indeed have a lot of stuff inside apart from the 980ti: 1x Geforce GT 120, 1x DVD-RW, 1x m2 SSD (via PCI 512GB), 1x SSD(512GB), 3xHDD(3TB/2TB/1TB), 1x USB 3.0 Card.
Now it makes a lot of sense to me, that this is supposed to be power related in the first place.
But something maybe even more evident:
I found this contentful video on GPU Setup (https://www.youtube.com/watch?v=2AIPw2jCr9o) and just the kind of adapter that is explicitly to be avoided for all the times is the one i used to connect my card, which is a mini 6-Pin to 8 adapter (gives a good chance to burn out the power port on the main board). So first, this is the one to remove and to replace with one of the solutions shown in the video and then see what happens. The second thing would be to withdraw some drives or the GT 120 i guess.
Best Answer
Firstly, I would be a bit wary about running a 980 Ti with the stock power supply in a 2010 Mac Pro, power draw might be an issue. It's a 250W card, and the 2010 Mac Pro has a 980W stock PSU. If there's a lot of extra draw on the PSU that might cause it to trip out, which could be a factor if you've upgraded the hardware.
Secondly, do you have CUDA installed? Try uninstalling CUDA. I encountered a similar situation last year, but I don't recall the exact panic text. If uninstalling doesn't help, CUDA can be easily reinstalled afterwards.
