On the subject, Alienware are suppose to come Overclocked, and can't be changed by the user. Its all under lock down. Overclocking, just edits your settings to make your card run faster, and use all of its potential, however if it can cause issues if done incorrectly. If you contact Alienware/Dell they should be able to tell you if your system is overclocked or not. But if I remember correctly when I called them, all Alienware Laptops come overclocked to the maximum they can with it still being stable and not causing issues.
