Well, maybe for people who want to run a store with several displays more than one or two graphic cards could make sense. But i think this is only advertised because it is possible - not because it is necessary.

What i find as well very interesting on those Mac Pros ar ethe two Ethernet cards that are there - so you8 can have a network AND an ethernet printer on the machine without needing a hub.

A super interesting thing of course is the option to run Windows on that. Part of my busioness is doing PowerPoint presentations. Mostly for clients with Windows machines. Now i can do that on this machine without using an emulator and performance loss. As well for tests this is excellent - i can check wether bugs are Mac only or are Mac and Windows. For me this is brilliant. For you it might be interesting to use video editing software that only runs on Windows on this machine. Could be another interesting aspect.
