What is really sad is not that this guy doesn't know much about why AMD and Intel have dual core processors, the sad part is all of these people are claiming to be better than Wrong because of his lack of knowledge, calling him stupid and so forth over and over. Instead of bashing on him like the previous 2-15 (or however many people posted before you) just explain to him why it is better to have two cores. You don't know Wrong, maybe your bashing and name calling can have some kind of affect on him. Oh and before you go claiming your superior to everyone else like most of the people in this thread has, check out your own intelligence, for example your grammar/communication skills most of you "superior intelligant people" have.
