I must admit yours is the first objective post in this thread.
The problem with my dual system is that the software uses one CPU for mixing and the other for recording. So many times one processor was barely used whily the other was over 90%. So my experience with a dual system has not really impressed me. I've read that a dual processor will only give you about 20% extra performance.
Wrong - a dual processor system will use up to 20% of its overhead, depending on how it is controlled.
And it is a fact that Motorola has problems in speeding up the processor.
Problems? Like what. Every chip maker has the same challenge....not problem.
So I really honestly wonder what will be Apples next move....
Maybe you won't have to wonder much longer. Man, why don't you pick up a book or something. Taken from Ace's Hardware:
2.5 GHz PowerPC 970? (CPU)
By Brian Neal

Thanks to Gabriele Svelto for posting about this link discussing the upcoming PowerPC 970. As you know, the PPC970 is a single-core derivative of the POWER4 featuring AltiVec extensions and is also highly rumored to be at the heart of future Apple systems. When we first reported on the 970 last year, the target clock frequency was 1.8 GHz and the SPEC CPU2000 performance estimates were 937 SPECint2000 and 1051 SPECfp2000 (presumably Base not Peak).
However, IBM has raised its previous estimate and is now specifying the chip will run at a range of frequencies between 1.8 GHz and 2.5 GHz. The top end of the range is quite a significant improvement in clockspeed relative to what was expected previously. From the link:
The new IBM PowerPC 970 is the heart of the PowerPC Blade. It is based on the 64-Bit Power 4 architecture which is also used in the processors of the IBM eServer pSeries. The 64-bit microprozessor
· Offers full symmetrical multi-processing
· Has a high reliability (with parity L1, ECC L2 and parity checked system bus)
· Is manufactured in the latest 0,13 micrometer Copper/SOI CMOS technology
· Runs at frequences ranging from 1.8 GHz - 2.5 Ghz
Therefore the IBMPowerPC 970 is the fastest PowerPC so far.
While Apple has long been suspected of being a likely customer for the new chip, here we see that the 970 is also being targeted for server blade applications. The new PowerPC Blades will be able to be used alongside IBM's existing x86-based blades in the eServer BladeCenter chassis
Update: Thanks to Alberto for posting this link from ZDNet indicating that the PPC970 will require a shrink to 0.09µ before reaching 2.5 GHz. This means 1.8 GHz, or a frequency relatively close to it, may still be the fastest 0.13µ 970. The article also indicates that the chip will dissipate 42W at 1.8 GHz. More details can be found in this presentation from MPF 2002.

I personal think the discussion having a Mac or a PC is useless. I mean it's verry hard, if not impossible, to get a real objective discussion.
So why are you still here?
