That particular model of cpu dynamically clocks itself up to 3.8ghz in dual core operation whenever it needs to, using hyperthreading.
The virtual cores created using hyperthreading will be used whenever there's a program or task that is fully capable of scaling to 4 threads. The performance gain is around up to 20-30%, depending on how fully those fake cores are used.

My bad I meant to say turboboost for my initial statement. It dynamically overlocks itself to 3.8ghz.
Quad cores (lynnfield series in particular) have more headroom to overclock, so you get much greater clock rate increases out of it. The lynnfield i7 870, for example, can from its 2.93 default clock all the way to 3.6ghz clock rate while in single core and 2.53ghz while in dual core.
