LCDSysInfo for GOverlay: A $32 LCD gadget for PC enthusiasts and tinkerers
As a PC builder and gamer I find it fun and incredibly interesting to monitor many things in my set-up, from the temperature of my CPU and its fan speed, to the frames per second and GPU load in games, just to see how capable my PC really is.
Traditionally I'd use a bunch of programs to monitor all these stats, including SpeedFan and Fraps, gathering info through pop-ups or windows on a second monitor. Then I was sent an LCDSysInfo - a small 2.8-inch LCD gadget that can be configured to show various stats - and monitoring my PC became significantly easier.
