I have what may be a simple question. I know the megahertz myth and how it relates to computers, but I do want to know why we seem to have slowed to a crawl moving past the 3Ghz mark. In the summer of 2004 i got my 2.5Ghz DP G5, later in 2007 replaced by Apple to a MacPro 1.1 2.66Ghz Quad. I've had a 2.53Ghz Pentium IV HP since about 2003. The thing can barely chug along anymore. Yet over the past 7 years we've been dancing around the 3Ghz number and just adding more cores. Will we ever see a 4Ghz processor? I am not complaining, I'm just curious and I'm sure you guys can answer this for me. Thanks!
