Generell Question about Multiplayer Server


I’m just about to learn some principle stuff, for example how networking works I understand the Server-Client Technologie and I’m just wondering, if I have a MMORPG for instance with a Server where the User connects as a Client…does the Server actually have a GPU which is used in some way? The Server is actually not rendering the game so it shouldn’t take any advantage if the server have a GTX 1080 for example?

The reason why I’m asking is beacause I’m thinking about to buy a PC (just 400-500€) to simulate a server just for development, so other developer could join the server as well. So if I could save the money for GPU I could spend it for more RAM or a better CPU.
