Maybe for the top-o-the-line card. If I were building a new machine
today, I would choose a motherboard with a PCI-express rather than an
AGP slot, which rules out some of the really old stuff; but just a few
months ago I bought some Quadro FX 1400 cards for ~ US$430 each. The
1400 is about 2 generations old and will handle map-fitting just fine.
These went into Linux machines, and they run O, Coot and PyMol. If you
absolutely must build large surface-mapped models and rotate them in
real time, then the newer cards might be helpful.
One drawback of the Apple products: you are restricted to the few
products they support, so you might not be able to pick & choose your
graphics card. You can expect the one they sell you to be supported very
well though.
If you want stereo, you'll need a large, fast CRT. They're getting hard
to find. This has been discussed recently on the BB so I won't get into
it again.
Dial boxes: I wish someone would build & sell a USB dial box. It's so
<CENSORED> obvious. The technology is very simple: 8 rotary optical
counters in a box with a USB microprocessor. Design it well and you
wouldn't even need a separate power cord, you could power it off the USB
bus. The biggest impediment is probably the small market.
