I don't have anything as exotic running here, but you will need amdgpu, plus (potentially) amdgpu-pro for your graphics: https://wiki.gentoo.org/wiki/AMDGPU https://wiki.gentoo.org/wiki/AMDGPU-PRO You will be able to confirm what is required in respect to firmware and kernel graphics driver components once you boot up with a liveUSB. It will complain of any missing firmware. For microcode, flash the BIOS with the latest OEM firmware and add the corresponding AMD family firmware file in your kernel: https://wiki.gentoo.org/wiki/AMD_microcode If you boot with the latest Ubuntu it will probably load everything required; then fish around dmesg and hwinfo, lspci, lscpu, etc. for relevant drivers and firmware files. > As a somewhat tangential question, would it be worthwhile getting water > cooling in my new machine?

You could invest the money toward more RAM, (more/bigger) case fans, a better PSU, monitor, speakers, a new car, etc. :-) https://www.techreviewer.com/tech-specs/amd-7700x-tdp/ Cranking up 16 threads to 5.4 GHz will produce some heat, but compiles will complete sooner too. I think an air cooler will be equally as effective thermally, with fewer components to go wrong. Either way, consider the space envelop in the case because some dual fan air-coolers can be rather large.
