When it comes to benchmarking for AnandTech, a KVM (Keyboard, Video & Mouse) switch is an absolute must. The idea is simple; you have one keyboard, one monitor and one mouse, and want to share it between more than one computer. You could always plug in your keyboard, monitor and mouse to any system that you wanted to use, and then unplug and move them to another system when you're ready to switch, but obviously that's not the most efficient way of doing things. Thus, the KVM was born. Used everywhere from benchmarking labs to data centers, a KVM is an invaluable tool for anyone managing more than one computer..
