when playing back more than 3 layers of video frame rate drope considerably, I'm going to retest with either a 10K scsi, or firewire 800 raid tomorrow and see. I also can see the 6600 as a limiting factor when using visual fx, it wasn't too bad, but I can forsee issues wen I'm doing more stuff.

thats pretty much what you can expect using the internal disc drive.
the cpu isnt the performance limit.
its the seek time on the disc.
you must always put your media on a separate drive - the os hits the system drive with requests for things like virtual memory paging.

you also might like to try one of the new raptor 150gb drives.

are you running at 30 or 25fps?
