You can get away posting this here, but I advise against posting this on any major hardware review sites (Xbit, Anandtech, Techreport, [H]ardOCP, etc) that have legitimate PC hardware knowledge. You will be ridiculed for your ignorance. If you want an honest, knowledgeable, and thus credible comparison I would refrain from even trusting that site you quoted, osViews. I have yet to see a pro-Apple site show even the slightest bit of the knowledge on current PC hardware technology, so in a way it is not surprising.
I went to Newegg (relatively mainstream online PC shop), and priced out 2 of the most important components in a "value" PC today:
A64 3000+ $146 Retail

Epox Socket 754 mobo $70.

A site that dares to post a chip from 2001, the P4 2.0, and then claim it is $145 and the "best they could find" is insulting. The A64 chip can hold its own against even dually 1.42's w/o sweating--only the 1.8+ G5's will even come close to challenging it. (and yes, the 3000+ is only running @ 2Ghz)
They present a RDF that rivals even Job's, and that is saying alot.
*lol, upon scanning their front page, I see a Balmer article and a "FUD" article. This pro-Apple site is not going to expand your knowledge but limit it (from a pure, PC hardware perspective).
