Can somebody tell me how important the system bus speed is when compressing and working with video? I am looking to get a G5 soon, but am not quite convinced about getting it until Apple and third party vendors begin to release true 64 bit applications. If my logic is correct (and it probably isn't), the things I see being advantageous in a G5 at the moment is the high system bus and higher MHz (which is very impressive, don't get me wrong, but how much of a difference will that make from a G4 system when running 32 bit code?). And I certainly don't have an extra $4950.00 to max out the RAM at the moment either! Or maybe somebody who owns a G5 (lucky...) can give some real world time stats when compressing from iMovie or Final Cut Express to QuickTime? Any stats will do. Thanks!
