Thorn, the prediction was
<< I say there won't be a 3D accelerator released in the next 18 months that'll really push a 700MHz P3 or Athlon to it's limits at a decent res (1024x768+) >>

18 months ago Anand was testing 16 MB TNT's and 3dFX Banshees, we now have 64 MB DDR GeFroce 2's. If we see a comparable increase in video processing power over the next 18 months, there is no way a 700 Mhz Athlon or PIII will keep up, not even close. QIII is a somewhat anomalous benchmark anyway because of the unusually large textures it throws around. Other games scale with CPU +'s even at 10X7 32 bit, how about sims which rely heavily on AI as well as graphics. Not to mention the entire WORLD of applications which many average people run in the areas of graphics, animation, music, databases, etc, that benefit from every extra bit of CPU horsepower.
Obviously there is a point of diminshing returns, the flagship processors from AMD/Intel are way overpriced compared to the next level or two down, but that certainly doesn't mean a 700-800 Mhz CPU is a complete waste compared to a 600 Mhz part. No matter what you buy, it will be somewhat obsolete, but still functional, in a year or two. Buying-up now simply pushes that date a little further into the future and how much you are willing to pay for that is really just a personal decision.
If a 600 Mhz CPU is $200, an 800 Mhz is $290 and a 1000 Mhz CPU is $700, I'd buy the 800. Sure, I'm paying about 50% more for a 30% increase in speed, but I don't adhere to that slightly goofy Modus approach to pricing computer components. An extra $90 for 200Mhz is OK, but I simply won't pay $700 for a CPU.
Edit: I may as well say something about the orignal topic, it sucks that AMD is locking these CPU's. It will make ZERO difference to a big company, they could care less. They buy computers from Compaq, Dell, whatever, they won't end up with a remarked CPU. It probably made my decision for me, a cBO 700 Mhz PIII with the Asus 815 MB. I was going to go for a Duron 600 and overclock to 950, oh well.....
