Looking for GPU recommendation for Linux compatibility, gaming, and programming (lemmy.ca)

I'm a long time AMD user both my GPU and CPU. I have a powerful enough PSU and a b550m-plus mobo.

I'm looking to do gaming, light AI work, computer programming, running Docker server services.

I have a Radeon 6900xt, but it doesn't work well with Linux anymore. amdgpu fails to load, and I can only boot by adding nomodeset to my boot entry.

With ArchInstall I even tried reformatting with xfs, ext4, btrfs, without encryption, with and without LVM, selecting both ATI OS drivers for all GPUs, and drivers for AMD gpus, with systemd-boot and grub.

Even Fedora on USB only boots with nomodeset.

Windows seems to boot fine.

I assume it may be a problem with system reading the drivers from the GPU.

I have onboard HDMI for graphics, but I've never got it working.

tbh, my 6900XT was too powerful anyways. I do game in 4K with my 55" TV on the highest settings, but it seems I was still barely using the GPUs full potential.

Funny enough, I seem to have had more problems with high end GPUs in the past than low end GPUs.

I agree with the other poster this seems like a hardware issue.

  1. Start with a general battery of hardware tests.
  • Memtest for memory. One or two errors in a full run is OK, more than that is not. A full run will take a few hours, just run it overnight.
  • Furmark for GPU. Look for visual glitches or crashes.
  • Prime95 for CPU.
  1. If those fail to point out the issue. Swap components into another system. This will allow you to eliminate (or confirm) them as the issue. Example, does this GPU have issues in a different system?
