Hello Im really really new to pc's clock speeds and all that jazz. I have two computers one HP mini Netbook with an Intel Atom (1.6ghz?) and an iMac with i5 Duo. A friend was going to throw out a 3.0GHZ Pentium Duel core? And said I could have if I wanted it for a small price. Would that clock be Noticably faster then my current computers thanks sorry for the really nooby question
