I accidentally posted this in the Macbook Pro forums. I guess mods are not around to move messages? So, I am getting a GTX 1080 FE and replacing my GTX 980 SC card (currently in a custom build Windows computer). Final Cut Pro X runs better on AMD, but will it run ANY better upgrading from the AMD Radeon 5870 (stock that came with the Mac Pro) to the EVGA GTX 980 SC? That AMD card is so old, I am hoping the 980 will be better at rendering.
