Is iPhoto graphic card intensive? On my Early 2008 MP every time I go to full screen mode (already evident in '09) the graphics card fan spins up and there is a discernible pause in transitioning. I think with Lion's big emphasis on full screen functionality, I will be annoyed to death with the pause and annoying fan's whirl. Is the 2600xt really that outdated? I don't want to get a card for gaming purposes but something that will remedy this. During the presentation you see how fast the applications respond and they're using a iMac. I thought with 8cores I would be at least on par but it could be the graphics card as well. Such a downer.
