Here's the guide I made after perfecting my trials. I can try to help with any issues you encounter, but since everyone has a different system, only so much I can do. Medium difficulty.
Let me know how it goes, if someone tries it. I use it, and I like it, but it might not be your thing. Check the screenshot in the link, to see if that's something you'd like.
Might work for ATI cards, if they have similar functionality in their drivers.
