How to read video card specifications? [duplicate]
https://forums.guru3d.com/threads/what-vid-cards-have-uefi-gop-support.370375/ Going by this discussion, NVidia GPUs of the 7xx Series and AMD 4xx Series or newer should support UEFI boot out of the box. Some older cards(i.e. GTX670) had enough ROM space and got updates to an UEFI compatible BIOS. So if you buy anything that's not older than those you're fine except maybe some special server cards.
