There isn't any current software that would greatly benefit from the extra processing power.
I hope I won't trigger an infinite loop by writing this.

But yes, there is current software that would greatly benefit from it (media players, encoders, web browsing / flash, emulators, ...). They are current, and often used, at least when you use MorphOS as your main system.

This doesn't mean the other points "against" Powermac G5 don't stand of course (consumption, noise, only a single core would be used on MorphOS and so on...).
I just strongly protest against this statement that no software would make use of it.
