Apple Ships Dual 800 MHz Power Mac G4
83 percent faster than a 1.7 GHz Pentium IV-based PC

Finally Dual processor Macs can harness the power of dual processing with Mac OS X

I'll wait until they get FASTER to upgrade :)

Can they really harness that power, or is this flim-flam like the dual processor Pentiums which are scarcely better than single-processor Pentiums?

If you're running OS 8 or 9, only specially enabled programs can really take advantage of the dual processors... Photoshop is one of them, much to my delight. OS X, on the other hand, is supposed to have native support for multi-processor systems. I'm waiting to try out OS X until more software has been released natively for it.

It didn't take long for all my favorite publishing/graphics software to come out PowerPC native (way back when! ;) ), so I'd best start saving for a new home computer soon...

It is my understanding that the performance of dual processor configuration is significantly less than a single processor of the same MHz -- at least it is that way with the Pentiums.

I've not noticed any sort of slowdown with non-enhanced software running on my 450Mhz dual processor G4... and the speed increases with 'enabled' software like Photoshop are very noticeable.

The dual Pentiums are a different chip architecture, running a different operating system, etc., etc... A diesel engine vs. a gasoline engine vehicle would yield much different performance characteristics, even if both of them offered the same "horsepower."

All the benchmarks I've seen on the DP Macs (running OS 9) show a marginal speed improvement with non-enabled software, and a very significant improvement with software support. I can only assume having native operating system support for the DP arctiecture would yield much more significant improvements.
