this is my reasoning why not go duel core. Unless u doing video edting all the time. All audio editing/Recording i dont see any advantange to a duel core compare to single. Then ppl say but it is the future! yeah and that future about 3-5 years from now there will be much better duel core and that one u just will cost pennies!! now if u have the money now and will have money when the new duel core come out then go ahead. look 64 bit suppose to be the future, but we still using 32 bits and will be for while.
