    Does anyone know if it's possible to run a non-Mac native NVIDIA graphics card using the NVIDIA web drivers while also having the stock Radeon 5770 graphics card installed in a 2012 Mac Pro? It seems like having the stock card in the computer as well would get around the "no boot screen" issue with the NVIDIA cards that use web drivers. I plan on installing a Quadro P4000 card in my Mac Pro so I can run multiple 5K displays and since it's a single width card with fairly low power consumption, it seems like it could easily be installed alongside the stock Radeon 5770 as long as there isn't anything preventing them from working simultaneously. Is anyone running a Mac native graphics card with an NVIDIA card relying on web drivers? Will it work?

    Thanks!

    While it has been possible to run Nvidia and AMD together in a single system, I could be problematic and very much YMMV.

    There are posts that Mojave won't boot or be very unstable with both brand of cards installed.

    That's good to know. How are you liking your RX Vega 64? I've tried to find out how many displays it will support and the maximum resolution of each monitor but the AMD website sucks when it comes to the technical details of the card. Do you get a boot screen with it? For my uses I need a card that can support a 5120 x 1440 display, (2) 1920 x 1080 displays, and a 4K display simultaneously. I'd really love if I could also run an additional mirrored 5120 x 1440 display along with the other 4 displays which is why I'm inquiring about running a stock card plus the Quadro P4000 but I could live without it if instability is introduced. Could the RX Vega 64 support at least the 4 displays I need it to simultaneously?

    I ran Radeon 5770 with Quadro K2000 for a while. It does work but I can confirm from experience that it is temperamental. Often (perhaps two-thirds of the time), it would double boot - with the 'final' boot producing an Apple report request because of a major system error. It's the report with words to the effect of 'Last KEXT loaded before meltdown.." - after the system was up then you were fine but I got rid of it because seeing that ugly driver/kext conflict so frequently made me uncomfortable with overall system stability.

    PS: using a Quadro P-Series will limit your ability to use earlier versions of OSX (nothing below OSX V12 if I remember rightly)

    I only use my mac for Photoshop, 2D and 3D applications, no gaming, so far the Vega 64 has been great. No boot screen for the RX580 or Vega 64. The fastest Mojave compatible card with boot screen is a flashed AMD R9 280X. I have run both a RX580 and 280X together, but have not yet run the Vega64 with 280X.

    I only run two displays. but since it has 4 ports it will probably run 4 without any issues. Try searching google for Vega 64 4 monitors, you are not the first wanting that many displays (and more..). I will upgrade to a 2k (1440) monitor soon, don't think I need 4k.

    For example there is a Gigabyte Vega 64 w 6 ports and their web page claims in can run 6 monitors simultaneously.

    I agree instability is a deal killer.

    I honestly prefer Nvidia cards over AMD as they are far better for 3D apps, but sadly Apple stopped supporting it natively years ago. I looked into running Nvidia and AMD together and often it seems not advisable, not to mention that there are no Nvidia drives compatible with Mojave.

    Assuming you have the proper cables/ power source and if you have a retailer such as BestBuy or Fry's nearby you could buy one to "try out"? Specific Vega 64's only need flashing to get the card fans to run properly.

    Please note, the Vega 64 draws too much power from the built in Mac Pro power connectors (high end Nvidia cards too). There are 3 known ways to address this:
    #1 Mac Pro Pixlas Mod
    #2 Using SATA power
    #3 Adding a Extra PSU.

    Doesn’t the vega also need extra power from somewhere?

    Oh yeh, I guess a "try out" assumes you have the proper cables and power, as it draws too much power to safely use the onboard power connections.

    My Mac has the Pixlas Mod, Vecchiarelli sorry about that omission, I updated my post.
