As another builder of a Linux gaming desktop, let me just say: nice! I ended up going with an Nvidia 3080 because I'm more familiar with CUDA than AMD equivalents (and I do still need to get work done). If it wasn't for that, I'd likely have gone AMD as well!
One thing that I'd love to hear more on is what Guix gets you as a package manager and/or as a distro. I'm not really following how it differs from other, perhaps more traditional, package managers.
I've stuck it out on Arch, mainly for software availability in the AUR-- i.e. getting out of repo gaming utilities like greenwithenvy and the glorious eggroll proton fork without having to navigate flatpak/snap/etc. My last experience with Steam in a snap on Ubuntu was particularly bad: the application wasn't able to see the mounted drives where I was installing games, nor was it able to detect proton-ge-custom. I've heard the flatpak experience is better, but I haven't played with it at all.
