Hi Warren,
is this a stereo system? This would be very cheap, a quadro card costst
usually more.
Cheers,
Ulrich

Performance enthusiasts:
Having finished the MacPyMOL universal binary (http://delsci.com/pre), I
couldn't resist running some benchmarks in order see whether Apple's
performance claims hold up with respect to PyMOL.
It seems they do: At equal Ghz, the iMac Core Duo provides 170% the
graphics performance of the old iMac G5, 141% of the single-threaded CPU
performance, and 239% of the multi-threaded rendering performance.
Even more impressive is how well this $1,300 all-in-one system performs
in comparison to a traditional $5,000 Linux Opteron workstation. The
iMac Core Duo provides 30% greater graphics performance than my Quadro
FX 3000-equipped dual Opteron and is within 10% in terms of raw PyMOL
number crunching power (surface calculation and ray tracing).
Wow.
So with respect to PyMOL, Intel-based Macs have at least a 2-3X better
price/performance ratio over dual-CPU Opteron workstations (at least
from a commercial vendor like Sun). If you don't need 64-bit computing,
these new iMacs are a solid choice for molecular visualization with
PyMOL.
