difference between core 2 duo and dual core

The I3 is not a chip that I have personally own or have used so I cant tell you what its like to use but I can tell you how it performs because I have benchmarked it against my core 2 duo and my other friends I7 and I5. but the core 2 duo is awesome as far as price to performance goes. I would still probably get a core 2 quad just because it actually can out do some I5s. In short the core 2 duo can depending on the one you get can do the same things as modern processors. but of course there is the occasion that my core 2 duo dose show its age from time to time, what I am talking about is in some games if I Alt+Tab it can hang a bit, but I don't find this a big problem by the fact that I only spent $26 NZD. What I have noticed over the 2 years that my friends have played with there core 'I' PCs is that my core 2 duo can do the same things as there processors.

we all play over team speak and tend to play the same games together. I play games on a core 2 duo system and I have friends that have got themselves I7, I5 and I3 systems and I also have my brother that play games with us on his laptop running an I5 and integrated graphics, he has the hardest time and cannot always play.
