I have an Nvidia 1080Ti in my main computer which is currently running Linux. I also have an old 980Ti in a computer that doesn't need such a powerful graphics card. I was thinking of getting a really cheap graphics card to replace the 980Ti in the old computer and then putting the 980Ti in the same computer as the 1080Ti. Would I be able to use both the 1080Ti and the 980Ti in the same computer? Would that result in better CUDA and AI performance?
