Re: Mac Pro 3.0 or 3.2 (sorry if this has been asked)

it depends a little bit on what you'll be working with... i think a single stream of uncompressed hd is around 160mb/sec... that is pretty easy to achieve, but that would be the flat out minimum to capture a single stream of hd.

if you were editing uncompressed hd, you would need double that to get realtime playback of something as simple as a crossfade between 2 clips.

in compositing you may composite several clips together, so it kind of depends on what you need... i guess if i had to give a target, 320mb/sec minimum would probably be a decent place to start. 320mb/sec is not too hard achieve and should give you a pretty wide array of choices. and, if you are working in hd, quite a bit of your footage will probably be compressed, and that will have a much lighter data rate.
