Apr 27, 2017 - As computer components get faster and more powerful, you may find yourself wondering if your once top-of-the-line Mac Pro can be king again. Always check the compatibility of your editing software with your video card to ensure that GPU rendering and multiple GPUs are supported. A comparable, compatible AMD or NVIDIA GPU can be used. The GeForce cards listed above are a baseline.

Verify which model of the Mac Pro you own. If you own the 1,1 or 2,1 Mac Pro your options are limited to a few GPUs:. Nvidia GT 120. Nvidia 8800 GT. AMD Radeon 7950, 7970 or R9 280X if you have installed OS X Mavericks or newer via hack methods. We do not provide these methods, but information about them is readily available online. If you own the 3,1, 4,1, or 5,1 Mac Pro you can utilize any of GPUs we sell except for the GT 120 and 8800 GT mentioned above.
Please be aware that while the 3,1 Mac Pro has the same GPU compatibility as the 4,1 or 5,1 that the older hardware of the 3,1 will result in some comparative bottlenecking. In general I recommend the GTX 770 as the high end for the 3,1 Mac Pro as it maintains its price/performance ratio. If you prefer the ports or other features of a more powerful card it may still be worth considering.
