GPU for Mac pro 5.1 for bootscreen

[Krishest]

I’m combining two interests in one mac pro 5.1, gaming (windows 10, GTX1080 GPU using bootcamp) and music production (high sierra, manly running Logic pro). The question i have is what gpu to use for mac os. I want one that can run on low power, preferrably only the 75W from the pcie connection. It only needs to be able to boot from and run my 27» monitor. It needs to be compatible with high sierra without drivers or any other tricks. Would be good to have hdmi or displayport. Do anybody have a good suggestion?

The newest GPU that has a bootscreen natively is 7-8 years old, you're going to need OpenCore. It's pretty easy to install if you use Dortania's (IIRC) OpenCore Install Guide. Then you can use any macOS compatible card eg: Radeon VII, RX 580, Vega 64, Vega FE, 5700XT, 5600XT. No NVIDIA cards are supported except from Kepler (2012) and Kepler Refresh (2013) GPUs which are the GTX 600 and GTX 700 series respectively. I know that people are using GTX 680's and GTX 770's on Big Sur with OpenCore but as I said above, they are 7-8 years old.
