Hey guys, I'm thinking about switching out my dual RX 480's for a single GTX 1080 Ti. The lack of Apple support on AMD's front (vice versa) and the newly acquainted support from Nvidia is making me seriously consider a switch. I was wondering if anybody has a 1080 Ti running in their Mac Pro...

The Mac Pro 4,1 & 5,1 have plenty of PCIe AUX power, unless you need more than 300 watts for your GPU(s). Remember you get 75 watts from the PCIe slot. Each PCIe AUX 6 pin connector in the Mac Pro towers delivers 150 watts. Yes all three power pins in both of the PCIe AUX plugs are connected...
