I am looking to builing a vj rig and am having trouble finding all the most relevant information. I want to use 1 G5 and have up to 5 projector/screens hooked up to it. I am at a loss to find a new, cheap(!) mac video card that outputs fullscreen video. Then can anyone tell me what the highest quality codec/frame size is feasible? What is the main bottleneck: harddrive speed? Codec decompression/processor speed? Bus bandwith? Of course with any live video work the fastesd is the best, but what could a 1.6 Ghz G5 handle?

I know a dual 1Ghz G4 can handle 4-5 DV streams layered across 2 screens, coming off one fast firewire drive.

thank you
