This is another new nifty feature that will give you a couple more reasons to hit that power button. The Q-Button or Turbo Key is a little application that's automatically installed once you install Asus AI Suite (Note: You need to restart your computer once in order to use it). Once restarted the little Q-Button logo will appear in the task bar. You can choose between two other functions like AINap, which puts your computer in sleep mode, and Turbo Key that overclocks your CPU on the fly by 5MHz and also bumps up the core voltage a bit.
