I’m combining two interests in one mac pro 5.1, gaming (windows 10, GTX1080 GPU using bootcamp) and music production (high sierra, manly running Logic pro). The question i have is what gpu to use for mac os. I want one that can run on low power, preferrably only the 75W from the pcie connection. It only needs to be able to boot from and run my 27» monitor. It needs to be compatible with high sierra without drivers or any other tricks. Would be good to have hdmi or displayport. Do anybody have a good suggestion?
