Unparking Cores?

I ran across a vid on Youtube, and some guy recommended a program that unparks your cores by modifying registry settings.  Here's a link to the video...

And here's a link to the website if you wanna read up on the program, access the source code, or download the actual program.

The guy in the Youtube vid said he experienced an increase of 10-15 fps in cpu intensive games.  Feel free to share your thoughts.

Why not disable power saver settings?

Already did.  That's one of the first things I do once I install the OS.  I opened up the core unparking program, and it still showed that the cores were parked even with the power saver settings disabled.  I unparked the cores through the program, restarted my computer, and it seems to have worked.  Not sure about the FPS increase though.  I'm not very good at doing benchmarks.
