Description: This sidebar gadget for Windows is an easy to use application that allows users to monitor their system's performance. It's called the Quad / Dual Core Usage gadget. What it does is that it lets you keep the utilization of the individual cores as well as read their temperatures. With its new updates, there is now a dual core mode and colored backgrounds have been added to liven things up. If there is a core that has a temperature of 0 ℃ it won't be displayed anymore.
