Dude, the core is most definitly NOT at the end of its life. AMD has 2.2GHZ cores out there, people are OCing using LN2 to 2.6GHZ. Unless someone can provide me with proof that the 10-stage K7 at 2.5GHZ, is the limit and that a P4 with 20 stages will go 4 times further.
The K8 core is also an updated version of the K7 so that itself proves that it is not at the end. If AMD can add 512K L2 and 333MHZ FSB, it's because the chips can somewhat stand the heat and go further. I am sure you can get 0.09m AthlonXPs and they could scale beyond 2.8GHZ, so no, it is NOT at the end. It has been said SO many times, with Raystonn against Matisaro and the beyond, and yet most have been proven WRONG. Current Tbreds do not OC well because of a core design problem. If it is at the end, then how the hell is Barton adding more core components and scaling?
Price performance my friend, believe it or not, will remain AMD's strengh forever. Never have I seen an Intel chip on the same level of performance against an AMD one being below cost. When you see P4 1.6GHZ below AXP 1600+ pricing, and move on to the XP1800 and further ones, you will notice Intel is far from ever doing so.
