[X4U] Where dedicated GPU shines

[n]

Is gaming really the main place where the dedicated GPU of the MacBook 
Pro shines, or is it in any area related to screen re-draw?

I've been reading comparisons of MacBook Pro versus MacBook, and while 
I expected the "Pro" model to be dramatically faster, it really isn't.
The articles' main comment is something like "the main difference is 
that the MBPro has the dedicated GPU." Examples given of where this is 
key is in gaming.

Which is great to know, except that I'm not a gamer...

"Damnit, Jim! I'm an artist, not a gamer!!'

thanks!
