part of this is also the hardware issue of AGP (8x) versus PCI and=20 PCI-express interfaces being used by newer cards on newer boards... so=20 the much higher bandwith of, e.g., using a Quadro FX1400 with a PCI-E=20 x16 makes it far superior (in my experiences, w/ linux) to the nVidia=20 GeForce 6800 GT... (talking >18k FPS versus ~13-14k FPS in glxgears!).=20 with regards to stereo capabilities, after having used things like the=20 XiG drivers to emulate QBS with cards that don't natively support it=20 (e.g., ATI Radeon 8500), i would definitely opt for the card that=20 provides hardware stereo (so i'd rather use the nVidia Quadro 700 XGL=20 rather than the technically superior (but stereo-less) GeForce 6800+XiG=20 summit drivers (or whatever).=20 cameron =3D=3D=3D Wang Chern Hoe wrote (on 07/27/2005 08:55 AM): =3D=3D=3D >Hi Philippe, > >If you are using the Windows platform, I suggest you get a Geforce 6800U= ltra, and use rivatuner from http://downloads.guru3d.com/download.php?det= =3D163 to modify the driver to Quadro FX 4400 under Windows XP.
