Ok ... so there really isn't any way I'm going to see the difference unless I encode a movie?
I do a lot of graphic design work with large programs like Photoshop and Illustrator running together. I also have other programs (SmartFTP, FontExpert, Acrobat, etc.) and browser windows open at the same time. For the most part I just do a lot of multi-tasking, having Firefox open and NoteTab, for instance.
Well, that's one good thing at least.
