Can the HD 5870 coexist with the default NVIDIA GT 120 in the 2009 Mac PRO?

Any conflict between the NVIDIA and AMD drivers?

  • I currently have the original GT120 running in an Early 2009 Mac Pro along with a GTX285. Despite them both being based on the NVidia chipset, the performance isn't ideal. I've noticed video glitches and lower performance. While it will probably work, it's also probably better to avoid such a setup.

    Yes it can, you'd want to place the gt120 in the third pci-e slot and the 5870 in slot one.

  • Nvidia's and AMD cards never mix, despite what ever people think, it requires special motherboard's that enable it. All you have to do it switch out the 120 for the 5870 and then plug in the power to the 5870. The 5870 does not need any help seeing as its memory bandwidth is around 153.6 GB/sec versus the 120's useless 16 GB/sec. Basically just use one or the other not a combo, because in the Mac Pro mixing doesn't get you anywhere.
