The best I have seen for editing video is Final Cut Pro version 4 on the PowerMac G5. All of these new Macs have the firewire IEEE 1394 800 megabit per second input busses. These things relly scream. Sporting Dual processors and high bandwidth busses the opportunity for the DV data to bottleneck is greatly reduced. The Final Cut software is very versatile and is being used by a large number of movies houses and effects houses (ILM) for batch and pre-press editing. This stuff is the best that I've seen, but I am not in the business so there is probably other stuff out there equally good that I have not seen or used. Just my 2 cents.
