Just a quick question. I know daul core means two cores on one chip. But if you have a 2.0ghz daul core cpu dose it mean you are equal to or better than a 4.0ghz cpu? People keep asking me this. They want to know if they have a peice of software that requires a 3.0ghz cpu and they have a 1.5ghz daul core if they can run the software. I'm just not understanding single core to daul core thing completely and i am not sure if i am answering them correctly. I think so but just want to confirm.
