yeah mcdermd has all the COOL STUFF!

so fun fact,

350 to 500mhz in the G3 iMac, Apple used Motorola G3 CPU's,

the 600 and 700 mhz iMac used those IBM low power CPU's

Does anyone have an opinion on the performance of this IBM CPU?

Mine is not good, in 07 i acquired (2) 600 mhz iMac's

and they both seemed slower then the 500mhz iMac's

The GUI seemed snappier with the 500mhz over the 600mhz iMac with the new IBM cpu in it.

and the 500mhz iMac seemed to boot faster.
