    Not exactly. It's overpowered for *normal* usage (with this I mean web
    browsing , listening to mp3s , watching DVDs , etc).

    For people who work with computer science and computer related
    researches , every extra clock cycle is usefull. For example... Imagine
    that you are a network researcher and you've just written a new protocol
    for a wireless sensor network. Then , you start running it on NS (a
    network simulator). You need to gather data corresponding to 1 day of
    network usage. If you have , let's say , a Pentium 2 machine with 256MB
    of ram , this may take months. If you have a Pentium 4 3Ghz or a Athlon
    64 3200+ with 1GB of ram , this may take *only* one or two weeks (which
    is a considerable economy , given that usually programs dont work
    perfectly when you first compile them.. And is most considerable when
    you need to run this simulation about 30 times to get data to write a
    paper about your project) .. And I'm not joking. I dont work with NS ,
    but my brother does.. His simulations usually run for two days only to
    gather data about 1 Hour of network usage...

    Or imagine you have a mailserver running Fedora + postfix + spamassassin
    + amavisd for a domain that has about 1000 users. In my last work , we
    had a mailserver (Pentium 4 , 2.8Ghz , 1Gb ram) running suse +
    postfix+spamassassin and it works fine. We know that we need a especial
    machine only for running amavisd (we were on a subdomain of the
    university. The main server for the university was a dual xeon server
    and it usually didnt survive the workload caused by amavis). So , 3Ghz
    may be the *minimum* in certain circunstances..

    So , it may be overpowered in some circunstances.. like for my mother ,
    who uses her computer only to read e-mail and browse the net (but she
    uses a 486 DX2 80mhz for that)... Anything above 400Mhz would be
    unnecessary for her...
