Is there any uses for a second monitor?

Yes.
However, there is no use for multiple desks.

Why the fuck would I play video games in a window? Are you retarded?

Plenty. Right now I have a video streaming on my main monitor and I'm using the other to shitpost, I also commonly use the second monitor for reference material while working on the main monitor (net admin stuff, web GUIs for network appliances, text editors for web dev/scripting, remote desktop stuff, etc.). I also sometimes use it for reference material with a game on the primary monitor.

>Playing with tile sets
fucking disgusting

If you have to ask, then you're not using computers in an enterprise setting.

No you need at least 3.
