Multiple monitors with a Mac Pro and Resolume

[ben2020]

Hi there!
I'm not sure the best place to put this question so I have put it in another section as well.
I urgently need to find out some information quickly so I hope someone can help.

I am doing a complex project which involves me projecting thirty 10 second video loops at a time using five projectors onto 5 screens.
To do this I am planning to use Resolume 3 and a Mac Pro.
I spoke to the guys at Resolume and they said it was better to use one graphics card with 6 outs than 2 cards with 3 because Resolume is 32 bit not 64 bit and using 2 cards would put more of a strain on the program.
I need the videos not to stutter and because Resolume has the DXV codec which uses the graphics' card processor can anyone recommend a good graphics card with 6 outputs for a Mac?
Unfortunately I can't use a PC and it can be hard finding Mac drivers for many of the higher end cards.
All the video clips are 1024x576.
If anyone has any ideas I'd love to get your feedback.
Thanks a lot,
Ben

three dual head cards are working just fine with modul8, giving me 5 screens and one for the interface. cant see a reason why it shouldnt work well with resolume. but I can download the demo and give it a whip just to see if the performance is much different. cards are Nvidia GT6600 with dual DVI-D

Thanks for the advice.
I have ordered a radeon HD5870 and am hoping that will work.
If not I'll be back on this forum

Thanks,
Ben
