Hey I am confused by the terminologies Dual Core and Core 2 Duo, can someone please tell me something (not so technical) about the two CPUs? Some sales person in a PC shop told me that Core 2 Duo has chips? cores while a dual core has 2 chips? Is this informations right? Someone please reply as I am planning to upgrade from my ancient Pentium 4 machine to a new one and would like to get as much bang for my cash. Thanks.
