I am running RX 570 with PCIe + 6-pin connector for the power. These works out-of-the-box due to open source drivers. Older Nvidia cards work too, but you would need to go with older cards as you need Nouveau driver. I believe someone recently used AMD RX 6700XT, which is a bit insane.
The bottleneck here is SoC, not the GPU. With HW decoding on the GPU I can play 4K 60fps trailers on Unmatched just fine.
