You can always build a PC and not have to deal with that UEFI signing stuff as you’re expected to provide your own OS still, that option hasn’t been eliminated yet.
Also, AMD cards are more friendly to Linux users than Nvidia cards are, even with the existence of NVK for the latter; NVK only supports Turing and newer cards and Maxwell, Pascal, and Volta are too old for it, and since Nouveau is broken on Maxwell and newer by firmware signing, once those cards lose support in the proprietary drivers, unless NVK gets backported to them somehow, you’ll be SOL in the near future for 900-series, 10-series, and the Titan V, while Kepler and older is still supported by Nouveau, meanwhile over at AMD, Mesa actively supports Radeon cards going back to GCN1.
Basically, if you still have an R9 Fury or an RX 580 sitting around, for example, those cards will still be actively supported by Mesa open drivers for the foreseeable future, meanwhile your GTX 980Ti or 1080Ti, at least currently, are fully at the mercy of Nvidia’s closed drivers.
