The single biggest improvement, though, was getting a new, 4×4K display card. You can buy a card with lots of outputs, or you can buy a fanless card; never both. Also, you can have multiple video cards, or you can have a happy life; never both. Now I have a VisionTek Products Radeon 7750 SFF, and at night, when I sit on the couch next to the computer, I can hear a slight noise. If I never have to see another xorg.conf file, it will be a very good trade.
