I’ve had a bunch of issues with my GTX 1080 before I switched to an AMD RX 5700 XT. I love it, but I recently put the 1080 back in use for a headless game streaming server for my brother. It’s been working really well, handling both rendering and encoding at 1080p without issue, so I guess I’ve arrived at the same conclusion. They don’t really care about desktop usage, but once you’re not directly interacting with a display server on an Nvidia GPU, it’s fine.
