From AMD's upcoming chip roadmaps we know the Phenom II is due out early next year, and it's AMD's second 45nm chip, but in a recent show and tell session AMD demonstrated the "overhead" built into the chip by overclocking one to a crazy 5GHz. It did take a special CO2 sublimation cooling unit that carries the danger of suffocating you if you use it in a small room, but what the hey. With a liquid nitrogen cooling system the chip was easily pushed way over 5 gigs. You may think "yeah, I could overclock anything with that stuff!" but it should be noted that with fairly normal high-end air-cooling the chips could get up to 4GHz. It'll be interesting to watch AMD's battle with Intel's i7 play out. [PCPerspective]
At this point I can use photoshop on my laptop while other programs are open. That was my power criteria.
I'm not saying there arent users who need more power, but I can't help but feel that there is a tremendous amount of effort is being wasted on the top .5% of "power-users".
