GTX and RTX in one machine

Is it possible to run a 980Ti and RTX 4000 in the same machine? I’d like to test out tensor cores on the RTX 4000 while keeping a 980Ti in the machine.

Shouldn’t be a problem, both gpus are supported by the latest driver. You’d just have to set up xorg.conf to use the correct gpu to display and CUDA_VISIBLE_DEVICES to use the correct gpu you want to use for cuda.
