Hi all I just got a Mac Pro 4.1 2.66 Quad, 12GB DDR3, GT120. I want to move some parts from my gaming PC to the Mac Pro ( EVO 250GB SSD and GTX 970 ) I know the GTX 970 (with the right power cables) will work in a Mac Pro but im not sure if it works in High Sierra?? I also thought about selling it to buy a flashed card instead. I need to run Windows sometimes for gaming and dont know how to switch to Win10 without boot screen? Other upgrades I want to do in the future, flash it to 5.1, 6 core cpu, more memory, USB 3.0.
