Can anyone tell me how well (in lay terms) the macbook runs WC3 on an external monitor (19" - 22" flat Dell)?? Im in the market for a new computer and this is the set up im thinking about getting. A blackbook with external 19" Dell monitor. I dont do much gaming at all, however I do use Photoshop and iMovie regularly. My biggest concern is that the graphics chip in the Macbook will cause excessive lag while connected to an external monitor. I've seen the specs so I guess I'm just after some real world experiences from people with similar set ups. Really just hoping it blows away this 1.33 G4 ibook with 512 memory I've been using! Any advice, thoughts, or help is appreciated
