There is a lot of controversy from several sites about the Athalon 3000+ on the processor and it's specs, etc. These appear to be user opinions and The Inquirer has brought them together in this article, which raises a lot of good questions.
Unfortunately the article on Tom's has some glaring errors. For example, how can a ClawHammer have a TPD of 80-85 watts when the power converters only supply about 70? See here that this is to also support the Opteron, which presumably draws a bit more power...
