modern cpu's and gpu's have power saving built in so when they are idle they automatically under volt and under clock.
modern over clocking techniques often involve raising the 'turbo' speed of CPU's and graphics cards but with CPU's at least it is optional whether you choose to go for a turbo overclock or a standard overclock.
diehard enthusiasts wanting to get the highest clock speed for benchmarks will often disable the power saving features of the processor but for an average user you should definitely leave these enabled to save on your electricity bill and go for a modest overclock either turbo or classic.

I have my i7 950 overclocked to 4GHz (from 3.06 at 1.3v) with the power saving (Intel speedstep) enabled so that the clock multiplier and voltage are dropped for light to moderate use. This give me the speed when needed and the power saving when i don't
If I wanted to run a higher clock then i would have to disable the speedstep as the OC is unstable past 4GHz with it on.
The OC is really noticeable when doing CPU intensive task, most commonly for me is encoding DVD to AVI. It also helps in games, especially those that don't use all the cpu cores.
I've never noticed much benefit in games, but it makes quite a difference when I run Folding@home GPU client.

I think I will be keeping the Speedstep enabled then since I don't need extreme overclocks.
I will be aiming for my 4770K to be running somewhere near 4.4GHz unless I am unlucky with the chip I have got. It is good to know it will fall back to the power save mode when not gaming however. Skyrim only uses a couple of cores so it should stay in the boost state for longer, especially with the extra radiator cooling I have.
It sounds like I can mostly ignore the ROG OC profile tools then if I will be leaving the power saving on the CPU.

You can use the Asus Automatic over clocking tool and work your way down on the voltage until it's unstable. That's how I got 4.6GHz at 1.21V on my 3570K.

Thanks - I had managed to follow some of the more technical guides and I have my 4770K 4.5GHz stable at 1.25V at the moment. Load temps are in the mid-40s too so I can push it higher if I need to.
