Hi,
We have to assemble one special PD/GEM Performance Computer and also I always got some questions about Computer best for PD performance.
I Started a Wiki which discuss dedicated PD Computers (also embedded ones). If someone has made some special hardware and/or experiences, it would be nice it will be shown there... http://puredata.info/community/projects/pdcomputer/
My questions now:
a) Quadro vs. geforce: If I want display on multiple large screens, (is there) what is the benefits of NVIDIA quadro cards to geforce (eg. 6800 SLI) on signal quality rendering benefits. ?
Have you considered some of the other "workstation" class cards from 3dLabs or Appian. They need Accelerated-X from xi graphics (www.xig.com) and not standard xorg or X86free. But what I understand from their website, xi's X implementation is also very good for ATI and Matrox cards. Does anybody have any experience with that? (they claim performance massive performance gains, even beating ATI's binary drivers for windows and linux in benchmarks)
I have no experience with this stuff, Nvidia card. But I thought I should mention that there are alternatives to Nvidia chips.

Which feature are most important projecting on big screens ?
b) If I do 4 projections on a big screen so they are merged to one picture, must the video be displayed in frame sync (maybe using more than one computer) from the beamer/videocard view (not the video frames as content). ?
