In fact it will use 6 cores - but from what I can tell does not use hyperthreading, so best bang for your buck may be a 2500k as a 2600k with hyperthreading may not help - certainly my cpu only uses 6 cores - the other 6 hyperthreads lay dormant (The only thing I have that uses them is for video encodding - then they work !!).
