A quick search reveals that there are many available dual P4 (Xenon)

Umm.. they did test dual Xeon P4 systems, in fact the main bake offs
in the keynote were against dual Xeon P4 systems.
The Xeon is a hyped up P3, not P4. I'm not sure what the P4
equivalent is called (Xenon, as suggested, perhaps, although I've
heard 'P4 Xeon' used), but it certainly wasn't what Apple were
comparing with. So far as I know, it's almost impossible to get a
general-use 'Xenon' system, because they're not made in volume (lack
of demand, it's rumoured).
Intel has "Pentium III Xeon", "Xeon" and 'Xeon MP" processors as they
call them. The P3 Xeon top out at 900MHz the only Xeons currently top
out at 3.06GHz. The later two have features similar to the P4s (hyper
treading, etc.).
I think you are confusing Itaniums into this... most folks skipped
Itaniums completely until the Itanium 2 came out (even that isn't
selling that well yet). Itanium is not sold or priced as a desktop CPU
however the PPC 970 and P4 are (however P4 doesn't support SMP unless
you get one of the Xeon variants).
Apple tested against the Xeon 3.06GHz in a dual CPU configuration, they
used Dell Precision 650 systems.
PPC 970 would hold its own against the Itanium. Against the Itanium 2
it would be about even in integer performance and lag in floating
point. The Itanium 2 isn't very friendly in backwards support while the
PPC 970 is very friendly.
Also most Itanium workstations start at around 4k and have a fraction
of the features found in the new PowerMac G5, I bet an equivalent
system (in feature set) to the low end PowerMac G5 would easily run you
4.5k or more.
