Yea i agree it was not a fair test, what so ever. Even the fact that there was even a comparison between a Athlon and Celeron is an obvious demonstration, as far as for the Intel 1.8 p4 that was thrown in, yea that was just to laugh at how expensive Pentiums are. However I dont disagree with what they did. I work in computer retail at a major store, and constantly I have customers arguing with me over which computer is fast, the 2.6 celeron or the 2500+ AMD over there. (it looks even worst because thats just their PR rating and next to the PR rating is their core speed) Intel gave off an impression that megahertz count and thats it.(thats why the best computer in our store (best buy) has only a Nvidia 5200 video card, for over $2000?!) We all know thats not true, but thats how the passive customers see it. To explain all of the hop lala to a customer in the time that he wants to get in and out, most of the time, is not possible. So think of this as a punch back from AMD, who offer almost the same preformance as a Pentium 4 (not a celeron) for a much much lower price.
P.S. And now offers the best high end CPU that is out there, and still cheaper then Intel.
Edit*the reason I gave you that link was that you can get a sense of how fast Durons are. So as we can see from the test, even though it was unfair, it still justifies your purpose for buying a duron over a 1.8 p4 or a 2.6 celeron. And the 1.8 P4 isnt even $100, its $120.
