part of this is also the hardware issue of AGP (8x) versus PCI and
PCI-express interfaces being used by newer cards on newer boards... so
the much higher bandwith of, e.g., using a Quadro FX1400 with a PCI-E
x16 makes it far superior (in my experiences, w/ linux) to the nVidia
GeForce 6800 GT... (talking >18k FPS versus ~13-14k FPS in glxgears!).
with regards to stereo capabilities, after having used things like the
XiG drivers to emulate QBS with cards that don't natively support it
(e.g., ATI Radeon 8500), i would definitely opt for the card that
provides hardware stereo (so i'd rather use the nVidia Quadro 700 XGL
rather than the technically superior (but stereo-less) GeForce 6800+XiG
summit drivers (or whatever).

Hi Philippe,
If you are using the Windows platform, I suggest you get a Geforce 6800Ultra, and use rivatuner from http://downloads.guru3d.com/download.php?det=163 to modify the driver to Quadro FX 4400 under Windows XP. Thereafter, substitute O with NOC from http://noc.ibp.ac.cn/ and you should have saved several thousand bucks, increased your graphics card performance, and enabled 3D stereo on a Geforce card! The same goes for enabling undocumented features on an ATI card.
The only caveat is that this mod has not been ported over to Linux, and that
your graphic card's warranty will be ineffectual in the event of damage to the
GPU chip.
best regards

Hi Xtallographers, Oers and Pymolers,
In late January, Warren wrote: "The Quadro FX 3000 is the fastest card
I've ever seen PyMOL run on". Well since then half a year is gone.
So, would any of you had a chance to compare the FX 1400, FX 3400 and
FX 4400 performances for stereo under Linux, I mean for the usual
stereo programs we're using like O, Pymol or Turbo ?
From several tests I read it seems there is no serious gap between them
at least when compared for various engineering software (Rightmark, 3D
studio Max, AutoCAD, CATIA, Ensight, Maya, Patchwork 3D and
SolidWorks). As for their price there are some huge gaps on the other
hand...
Which of those 3 Quadro would you recommend in terms of
performance/price ratio for molecular graphics ?
In his email, Warren also recommended the NEC-Mitsubishi FP2141SB-BK
22" CRT. What do you Folks think about this monitor if you do use it ?
What do you think about the Iiyama HM204 DT DiamondTron 22" CRT ? Any
other good monitor for stereo around that you would recommended ?
Any help will be greatly appreciated.
Philippe
