I have a Mac Pro 4,1 with 5,1 firmware to get Sierra installed without any hacks. It currently has a Radeon 5870. I'm looking to upgrade the video card and want the best bang for buck route that I don't have to deal with constantly (if possible). I've read Sierra natively supports Polaris cards now so I was looking at an Rx 480, but I read that the last update killed it. nVidia cards I've never dealt with but I think require a web driver install after every OS update? Just looking for some advice on best route to get a "user friendly" less hassle - work like it should setup. Any help is appreciated.
I always recommende GTX680 cards. But they are not the latest. They are stable, run perfect in OSX. Have all port options. Are avalible in 4Gb configurations. Suppoert 4k in 60hz.
Pretty much what everybody needs, and fully supported. Realy easy to flash.
R9 280X i have also tried i few. They worked very well. But there are more problems and things to think about when flashing the ROMs for bootscreen.
If you want faster cards, i will let others speak.
