Subject: CCL:Question regarding Mac G5 performance

Folks, has anybody run QM or MD benchmarks on a dual-processor
2GHz G5 that they care to share?  I'm particularly interested
in how they stack up to the newest/newer Opteron and Pentium4
machines.  If you've worked with the newer Mac's, (a) is it
possible to get good, useful 2x processor performance for
double-precision code?  (b) what compilers are required to get
(a)?  (c) is Altivec useful for double-precision code, or
merely for int/float work?

A quick glance at apple.com suggests these machines go for about
$3200 USD, which isn't that different from numbers gained from a
quick glance at dell.com.  I know IBM chips were number-crunchers
in the good old days, and I assume that's still the case now (which
is why I'm looking to CCL for guidance :-).

Thanks in advance!
