why is the "overclocking" (i.e. "intel turbo boost") stuck at 2.8 GHz on the 4440S? it states here as well as the intel site that the turbo boost goes up to 3.3GHz, same as the 4440. is that just a mistype that you guys missed? but then you also state the same thing on the "reasons to consider the intel core i5 4440". and then the 4440 apparently performs worse on liquid cooling than air cooling on "overclocking"? do you guys have an editor or fact checker?
