Your review of the Athlon XP3200+ was EXTREMELY lacking.  You provided no evidence of it's performance.  You only stated that it "outran top Pentium 4-based systems on business applications."  Where's the proof?  You didn't provide a single score or bit of information as to how well it performed.  I realize PCWorld is not a hardcore computing magazine or website, but this is rediculous.  Your review of it goes against 95% of every other test done on the XP3200. 
I don't mean to be nasty, but if you'd like to check out websites that do REAL testing and show the facts, you might take a look at 
www.tomshardware.com and 
www.anandtech.com. 
I also notice that in the tests where you do provide facts (and few at that), you use computers that aren't equally equipped.  If you want to be taken seriously by the "hardcore computing" community, you really should refine your testing methods.  You can't take 2 completely different computers, run a few tests on them, and say it's a test of the processor.  That's insane.  So many other variables play a part in the complete performance of the system.
Years ago in my 5th grade science class we learned that when conducting experiments, you must have controls and variables.  Variables being the object, or in this case, componant that you're testing.  If you have a single constant, and 5 or 6 variables, that makes the experiment (or test) invalid. 
In the future, you may want to reconsider your testing strategies, or reconsider what you claim to be testing.
