I built a similar machine: * NixOS * AMD 5700G (8c/16t) * Nvidia GTX 760 (already owned) * 32GB of old ram at 3400 MT/s (was really surprised my old Micron RAM could be overclocked by 1000MT/s but I'll take it). * Old/existing 850W PSU Having the integrated Vega 8 graphics lets me run sway at 2 4K screens pretty much without issue. It's pretty simple on NixOS to configure PRIME such where the 'nvidia-offload' command can run any program on the Nvidia card. Sadly Vega 8 is only half the speed of my GTX 760... really wish AMD had included RDNA graphics like the Steamdeck. If I can grab a AMD GPU at a good price or Nvidia's GBM backend for Wayland support actually is released and works well I might upgrade to a 5700X or greater. It would be nice to have twice the L3 cache and even more threads when it comes to building some NixOS packages. Currently temperature reporting on the 5700G is somewhat broken on Linux 5.14. I can see the integrated GPU temperature (I think) which should be close enough to the CPU die temp. Using sleep (suspend to RAM) on the 5700G has issues with Sway/Wayland. System idles around ~50W which is about half that of my old 6700K system.
