I would also add that you need to consider if you are going to network or exchange files with other people to get projects done. If you are then obviously look to what apps they are using. C6Pro is a defiinitley a pro-capable app. Try the demos of the apps you consider - that is always the best and go to www.vtc.com and check our Mark Bremmer's Carrara 6 Pro training. The first several lessons are free and you can get a feel for the app that way.
