If this has been covered elsewhere, please feel free to link me! I'm using a 5 year old Mac Pro and I'm looking to upgrade. I'll be using it to make music and video. I do a song and video a day, so any speed increase seems worth my while. One of the things I've noticed about my current computer is that some heavy duty effects in Final Cut can take a REALLY long time to render, and that's a huge problem for me. Basically what I'm asking is if you all think that the speed difference between the 2.66 and 2.93 12 Core Mac Pros will be worth the not-so-insignificant price difference.
