Every time I get a new screen, it's good for about a few days before I realise I need another one.

How many monitors is too many?

I bought this to serve Minecraft:
HP Z420 Workstation E5-1650 V2 Six Core 3.5Ghz 32GB 256GB SSD Quadro 600 Win 10

Adding 1TB 870 Evo for Linux. Gonna default boot to Linux. I am hoping to serve up a few instances of various modpacks. Minecraft is single thread so I wanted decent per core performance.

All total I spent about $450.

Linux Mint MATE, Lubuntu or something else for this old PC?

Specs:
AMD Athlon 64 X2 5000+
2 GB RAM
Nvidia Quadro FX 1800

In the near future i'd like to switch to Linux on my primary laptop (HP EliteBook 8570w) - my uni requires it for the 2nd semester.
I've been thinking about Manjaro, or something else based on Arch Linux... The problem is - I've heard about how problematic is the installation of nVidia Graphics drivers. In my laptop I have the basic Intel HD Graphics with the 2nd Gen Intel Core i7, and an nVidia Quadro K2000 card.

My question is: will I it be really problematic?
