Hello All-

Regarding the expense of stereo graphics, I use a Nuvision 60GX-NSR
(non-stereo ready) driven by a GeForce FX5200 card to build in Xtalview
and have no complaints regarding the stereo performance.  I believe the
Nuvision setup was around $600 USD and today the FX500 costs the
staggering sum of $31.70 compared to the Quadro-based cards which seem
to be running $900-$1200 and, I believe, are required for stereo in
programs such as "O" and Coot.  Since it works with Xtalview/Xfit, what
is the reason that other graphics programs are unable to use the less
expensive graphics cards?

Thanks,
Tim Fritz

Hi,

If you build a system without stereo graphics, and use a standard
monitor, I 
agree. In-fact it can be done for for under ~$1000. However, stereo
systems 
are rather expensive (LCD stereo systems are VERY expensive).

I was just curious to see how popular stereo graphics is for 
crystallographers. I personally think its a wonderful teaching tool
which is 
currently under-utilized.
