Nov 14, 2017  Graphics Card Upgrade for Mac Pro 1,1. Discussion in 'Mac Pro. I'm using Yosemite already and I'm not concerned about the lack of boot screen – I'm just curious which cards actually work with the 1,1 since there's conflicting evidence in some of the threads here. Tried all ports. Had been using Snow Leopard. I just upgraded to El.

32-bit vs 64-bit. Hi Casey - aye I did - well, I got the: MSI GeForce GTX 970 GAMING Twin Frozr 5 Graphics Card - 4GB - You will need the Nvidia driver - get the one specific to your system - Needs 2 power cables. (I think card came with a 6 to 8 pin converter) Needed another mac to screen share to activate the Nvidia driver (in sys prefs), as you get a blank screen using the osx driver - luckily you get a basic low res view from another mac even without a card in. Boxford cad cam design tools serial. Not a massive improvement but a useful upgrade for a future hackintosh;-) Let us know how you get on.
