Using Arch GNU/Linux (Tried installing Debian, couldn't get the AMD drivers to work properly, so I'm using Arch for the moment)

Can run Stable Diffusion, LLMs, and basically all my games at 1440p High to Ultra settings (RDR2, GTA V, Arma 3, etc.)

GPU passhtrough doesn't work for the moment, but I can still run virtual machines. This is a Haswell motherboard, which can be 100% freed in the BIOS over time when we have enough Libreboot devs who can reverse engineer the rest of the blobs. Intel ME is also disabled (theoretically, since you can't actually fully remove it). This is a build that I did for fun, in the future, I'm planning on switching to a Z690-A motherboard with DDR5(can be flashed with Dasharo firmware). If you have any questions, feel free to ask!

You can encrypt your /boot partition with Argon2, which allows you to have a fully encrypted disk. You can check the integrity of your kernel at boot via Libreboot GRUB using GPG. Not as much spyware as you get with modern day computers. I know there is still proprietary ECs, microcode, etc. but we should all be trying to minimize proprietary software as much as possible.
