It's not very nice to call it a stupid argument, it's an opinion. I actually preferred AMD's products a while ago, but with the release of the 800 FSB P4's and Canterwood chipset, as well as AMD's fake PR rating as misleading selling arguments such as "AMD introduces XP****, world's highest performing PC processor".
I still think it's pretty pointless to purchase the XP3200+ or 3000+ when you can buy the 2800+ and overclock it, and you'll have the same chip. Or even the XP2500+ and overclock. You may like my argument or not, yet still it's an opinion. Now I don't usually make heavy overclocks myself because of some bad experiences, but such overclocks on eg: 2500+ to 3200+ speed has been done many times, with success. Besides, the 3200+ is way overpriced considering how it performs. The P4 3.0 with Canterwood is just about the same price as the 3200+ with nForce2, yet the P4 is performing better. That's why I wouldn't recommend anyone to purchase AMD CPU's that's faster than the XP2800+. You just gain too little considering what you have to pay for.
Wish I had the money for a P4 3.0 or 3.2 with Canterwood chip. I really want that setup.
