I'm planning on getting a basic Calculation setup including the following:
- Intel Xeon E3-1220V5: https://goo.gl/iEOxoW
- Gigabyte or ASUS H170M motherboad: https://goo.gl/5WaCZB
As you see, none of them have an integrated GPU of any type.
I will use this setup as a server 99% of the time, without any display. Though, I'll need a GUI (gnome or else) for easier installation and sometimes for very episodic use.
My question is, do I really need to install a very simple GPU, or can I run a low resolution GUI for time to time with just the CPU and the motherboard?
