Supported OOB AMD GPUs? For primary use as a boot-card on Sierra with RX 480.

Hello folks,

I'd be very grateful for your advice.

I'm looking for a GPU to use as a boot-card as a workaround for the Clover + RX 480 issue, where it is not able to boot up into Sierra properly. I unfortunately do not have an iGPU.

In case I'd encounter issues with configuring this dual-GPU setup, I also want to have a card that I can run MacOS Sierra with, thus /w accel. working OOB. I'm fine with almost anything that can handle the UI. A low-profile card would be preferred.

I had already looked around and I'm having issues finding something available, supported, and cheap enough either used or new. I'd also like to check if I had missed any model before going shopping.

Is any AMD GPU working out of the box with 10.12 missing from the following list?

5770, 5870, 6850, 7850, 7870, 7950, 7970, R7 260X, R7 270X, R9 280X
