While Apple might have said that, the main reason was that the PPC
architecture was running out of steam compared to Intel's stuff.
Apple had to pay IBM big money for producing the G5. IBM have
no incentive to compete with x86, other than in the
super-computing/mainframe segment, so money was the only way
they could be convinced. By moving to x86, Apple could get far more
powerful chips for much less. And sure, the G5 were HOT, literally.

The irony in all this is that PPC could have been a viable competitor
to x86, hadn't Apple sabotaged the CHRP(PReP) architecture back
in the day.

Sure is interesting to follow! :)
