We use 2 outputs thru the VGA card, make shure is at least a RADEON 9800 with 128 Mb. we use the RADEON 9800 PRO 256 Mb.

For 2 Video Layers and the rest as a Stills or Masks, you will be OK with a G5 2.0 Dual. Just need to have a good HD solution.

RAID Firewire 800 is what we use, i do know some systems have a SATA PCI Card, making also a RAID configuration, and gets even faster speeds.

V3. of catalyst will work great for shure, we did have those on our systems and just got upgraded to V4.

Richard can be more specific on the minimum req.
