from what I heard, those things caused a LOT of data corruption, mainly as the North-Bridge of the G3 was specifically made to only support 1 Processor per north-bridge from my understanding. Hence the reason in the gap between Dual Processors (dual 604x, skipped G3, then did Dual G4)
I don't think IBM wanted to try to work in Dual Processors since the PowerPC 750 (a relatively cheap design) would interfere with it's more Powerful CPUs that they were marketing in the server/mainframe categories.

To be honest, Dual G4's wouldn't make a difference, since in OS X it was practically unusable (OS X would only run one CPU, an inherent design of the north-bridge for the G3).

I wouldn't even pay the money for the novelty. I would just with either a fast G4, or a REALLY fast G3 on either a Beige, or a B&W G3 or Yikes!

Also, the tests they showed weren't that impressive...

Just from looking at the benchmark they posted it doesn't seem the second G4 makes a whole lot of difference over a single G4. The difference only amounts to about 12 or 13%, which you most likely wouldn't even notice. It's certainly not enough to justify the expense of buying one back when it was new and probably not worth the effort of trying to hunt one down now.
