[PD] hardware recommendation

Hallo list!

I have to use 4 800x600 projectors with 4 channel sound for an installation, so I wanted to ask if someone can share some experiences which hardware we should buy ...

the organizers suggested the following: athlon64, 1.8ghz 1gb ram 2x matrox g200 dualhead pci. (1 or 2 computers)

1. Should I really try to use the 64 bit processors :) (on linux of

course) ?

2. I think I will use GEM (it's not much to do - I have to display some

images and text ...), so I am just thinking about, how to use 4 projectors:

• I could use 2 computer with a dualhead graphic card, then make a big

GEM window over all 2 heads

• 1 computer with 2 dualhead graphic cards and make a big GEM window

over all 4 heads ?

• or maybe start 2 PDs on one computer to have 2 gemwins (trying to

avoid the experimtental multiple gemwin feature ...)

3. matrox g200: has anyone experiences with that card - I searched

google and found an (old) article, there it was said, that it's not possible to use DRI with 2 screens on linux ... or could someone suggest an other card?

Thanks a lot for any suggestion, LG Georg
