In my opinion, there's no such thing. They rely a lot on "AUTO" settings, and you really have no idea what they are doing.
Learn to use the BIOS. The following is my standard "noob OC'ing reply:
This should be your first stop.

This should be your second stop. You
need to know something about thermal management or you can fry your CPU. It's actually kind of difficult to fry a modern CPU, but it is possible.

Third stop will be a guide for your particular motherboard. Google is your friend.
You should be able to reach 3.0 GHz with the stock heatsink. For anything higher, you
will need better cooling. Here are two under $50 heatsinks that are pretty popular:

They both require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.
Go through the first two threads. Do not do anything until you have a good idea about what you are trying to do. Once you have definite questions (you will, you will
), come back and ask.
Keep in mind that these are guides, not cookbooks. YMMV. Your Mileage May Vary. Because of all the variables, you may not do as well as someone else with a similar system. Or you might do better.
Once you have achieved a stable overclock, turn SpeedStep back on. That will keep your CPU throttled back to 6 X FSB freq during periods of no load.
I have a Q6600 OC'd to to 3.3 GHz (367 MHz X 9) in my download box. Even while playing an .AVI file and downloading in the background, it runs 2.2 GHz.
