Ordered the GeForce 1070 today. I found it new for $475 and was assured it would work in my mac pro, so i’m giving it a shot. I looked at the 1080Ti, nut im uncertain that my system would be able to use enough of its functionality to make it worth the price… Kind of afraid the GPU might bottle neck on the PCIe 2.0 architecture of my system.
I figured quadrupling my current GPU specs with the 1070 was enough for the time being…
I have been out of the loop for a few years, so Thank you for your help…
