How do I overclock my monitor?

I've been hearing a lot about it on 4chan and reddit, sounds cool so what do I need to do to get started?

Um....are you talking about getting a higher refresh rate or something else?

Higher refresh rate, from what I understand. I don't know much about it but reddit and 4chan make it sound really cool so I want to know about it.

Get Switchres X. Create a custom resolution with a higher refresh rate. Done!

GPU? With Nvidia it's as easy as making a custom resolution in the control panel. Don't know how it's done with AMD.

7950 gpu, 1650(or maybe its  1680 been too long since I looked)x1050

not everyone is on a Mac.
