If this speed-similarity is the case, then i feel i should really consider the 800Mhz A1G3XE, because of the full 512KB L2-cache, and the CPU is from IBM. The 750FX G3 CPU is just 1 year old, being produced last year!
i had an ibm hard drive and what a load of crap that is just over a year old and not much good anyway the g4 is made by motorola and i have not had any problems with there stuff. The g4 has altivec which if os 4 uses would give it the edge over the g3 ?
