Graphics cards (GPUs) in Unraid systems are mainly used for two functions: Either you are using Unraid to virtually host your desktop computer and you play video games on it. Or you are running a Plex Media Server and need power for hardware-accelerated transcoding. Of course, there are other use-cases where a powerful GPU can come in handy.
