I agree with "imgod2u". Intel changes sockets, because they also make chipsets. When intel switches to a new CPU, they make a new chipset, and they make a new socket. Intel rules around 73% of the CPU market, and AMD owns arond 24%. AMD is staying on the same socket, so that companies can still run on an outdated KT133 chipset, and no one knows the difference. Not to mention, the enthusiest market is so small, if AMD and Intel cut overclocking completely, there wouldn't be much pain between the two.
I am an AMD fan, but I am also a competition fan. I appreciate AMD, as well as Intel equally. Right now I run an AMD XP1600 @ 1820MHz w/ aircooling. I am getting ready to upgrade to a 1.8GHz Northwood, and I am wanting to overclock to around 2.9GHz. I will be upgrading by 1.1GHz (but only around a 28% actuall performance jump), but I feel it is worth it.
I can sell my EpoX 8K3A, XP1600, and Thermalright AX7 for $190, and once I itcontact a friend of mine, I can move to a P4 @ 2.9GHz/P4B266-C/Good HSF for only around $75. Now in my opinion, that is well worth the $75 for the 28% performance jump. Once the hammer is out, I will likely upgrade to that, but for now, little $75-$200 upgrades after selling current stuff does fine for me. When hammer comes out, I'm going to spend $1500 to upgrade motherboard/CPU/ram/cooling.
With current top end CPU performance, and overclocking potential of 1.8a's, I see it futile to buy a 2.53GHz P4.
That's just my $0.02
