"Once Photoshop is programmed to utilize the Altivec enhancement,
shouldn't the performance improvement numbers add a zero and change?"

It depends on what you're doing. For big tasks: no way.

As an illustration, we can look back at Photoshop tests from a few years ago. For small tasks (small images), the PowerPC's won. For large tasks (large images), Intel machines won. Why? At the time, the Intel machines had faster memory (66mhz EDO vs. 50mhz fpm) than the Macs. The bottleneck was the memory, not the chip.

So, for hugeimages, Altivec will certainly help, but the memory bottleneck will dilute performance.
