You know the turbo button was actually to decrease speed of your processor in order to play games that run on processing clock speed. The original button was to decrease speed of the processor but marketing believed it wouldn't sell the idea of slow down your machine. So they reversed the button and call it turbo keeping it always pressed until you need to play a game that rely on slower processing clock to be playable.
