Linux on Mac PPC vs AMD64

[Richard <cms01@tampabay.rr.com>]

this may be a slight off subject,
however, I have a choice to purchase a dual g5 with 4gb of Ram,
or build a dual core AMD 64 with 8GB or Ram... the real question here,
is longevities.

Since Mac is dumping ppc is moving intel,
and AMD 64 is moving up the ranks... I was just thinking, if
I purchase the Mac, may have a problem of supported hardware
for ppc ???

please note: been a long time mac user since 1982,
however, open source is really taking over, and looking
to stay with the flow.
