Long-time PC/Windows guy apparently in over his head on my son's Mac Pro. My son does video editing professionally and, as a present, I've thrown a lot of upgrades in his Mid-2010 5,1 Mac Pro. (SATA III SSD, RAM, USB 3.1, High Sierra).
I wanted to upgrade his video card from the ATI Radeon HD 5870. I had done a good amount of research and landed on a NVIDEA GeForce GTX Ti (6gb). I've seen that others run this card on this same hardware. I installed the only NVIDEA driver that I could find and linked from other forums, but it doesn't work. From what I can tell, I might need to do something at a 'Clover' boot menu. Under this nor the ATI card do I see the Apple logo, so I don't thing I have a way to access that.
(Again, I'm a Windows guy). Any help with getting this to work would be endlessly appreciated. I think I got a pretty good deal on the card ($350), but am open to selling that and getting an equivalent plug-and-play solution depending on the $$$. I don't know if it's critical, but the ATI card has two 6-pin auxiliary power connectors. The NVIDEA card has an 8-pin and a 6-pin power inputs. I plugged the two 6-pin power cables into the NVIDEA card.
While the TDP of the GTX 980 Ti (250 w) exceeds the rated power available through the Mac Pro (225 w), in practice the power draw stays reliably within the limits of the Mac Pro. I'm comfortable running mine on internal power, but not everyone is.
