I'd advise getting a scandoubler. Those Multiscan/Productivity modes are death. They use so much custom chip bandwidth that the machine slows to a crawl no matter how fast a processor you have (so forget about using it for internet apps), and they suffer from quirks like the mouse pointer disappearing when you go to the far right of the screen, and wrecking screen dragging to non-productivity modes. Oh, and minimal overscan.
(Or, even better, get a gfx card ;-)
