Server does not need a great graphic card or bells and whistles. A quad is good enough but best to run at least a gen 7 intel. SSD and not HD if you can for storage and min of 8GB Ram best. Internet speed counts for this so. wifi not so good, should be hard wired and highspeed.
I always had good servers just not had time to start a new set again right now. Maybe look at the basic youtube quality in video and it will show how a server can work.
Heres my YT you can maybe get an idea how it will be with even a mid system if you look at the old GPBikes championship videos.
If I have some ASUS ROG arts if your looking for good shit lol.
Hope your get it sorted and look forward to riding on the server
