Intel quad core, what advantege it will be for user?

After possibility of see it, and see some tests i must say: Normal user would feel no advanteges in 4 cores. Its because of 2 cores at higher frequency are faster in most games, better in playing video etc. Its just because most of software isnt optimalized to use more cores, and than only advantege at 2 cores is fact, that system occupy one core, and game (or anything else) have full power of second core. But there is no difference if processor contain 2 more unused cores. Only in really specific situations it will reveal its huge computing power, but.. There isnt much users who need to run 10 applications which need much computing power together. So for normal user is better now save money, because 4 core is only expensive, and wont hepl him.
