ffakr, READ duke's DAMN POST MORE CAREFULLY before you go and slam him out the damn door. [Settling down...] He stated that the current new chip in the current new PowerMac is supposed to be, basically, a hold over until the newer chip, the Power4, becomes implanted in upcoming PowerMacs.
OSeXy, well put. I'm glad someone understands this whole damn ordeal.
elensil, you are a complete moron. Not to make this sound like a flame post, but...
Apple would have had put in faster chips and kept the old design if Motorola could produce the faster 7470 chips in both fast speeds and in suffecient quantity. But the [censored] there could not perform this duty. The result: Apple had no choice, but to overclock their current chips in order to get faster PowerMacs out the door.
Plain and simple: Apple is in the tightest spot you can think of with these PowerMacs. Once Apple gets the supposed Power4 going you probably won't have to worry about any of these "Yikes!" issues.
