I've read varying comments regarding this with respect to the Intel CORE CPU models that have it active. Early on, a review comment or two claimed to observe little effect e.g. with TrueCrypt. More recent comments I've seen have claimed to observe a much greater effect; IIRC TrueCrypt 7, recently released, is the first version to use the AES instructions when available.
P.S. Note, if you are interested in this feature, that not all levels of the CORE product line have it. For example, in the current mobile line, I believe it's present/activated only at the 520M level and above (although my knowledge is some months dated, at this point).
Ah, I see this information is echoed in the Wikipedia reference:
