Can Apple Just Do What They Need to With a Mac Pro?

I'm starting to really wonder if for the typical promac user, if they're going to need discreet, like external graphic cards. I don't know what the answer is there. And it's very technical, and it has do with apple's perception of that market. If pro mac uses using like er after effects and final cut, maybe premier or whatever, as long as they can make those specific things work really great. Can't applejists do it all on their own? i'll have to talk about this a lot more in the we have a year to talk about it.
