'Add remove programs' usually says 'last used'.

Its nowhere near a fresh install really. The brackets will need chaging, but the screw holes are the same, just use a slightly longer screw. So, old board off, swap the bracket, new board on. A 680 is only 5" diagonally bigger than a 580, so at first you'll have a 2.5" (ish) border around the screen. You'd be very unlucky if your projector has been fitted in a position such that it won't zoom out too fill that gap. Once it's all lined up, fit the new cable, and drill and screw the two bottom mounting holes. Fit the pen tray and orient, Done! The biggest problem you might have (assuming the projector doesn't need moving) is if any trunking, conduit, wall boxes etc foul the new bigger board, but the 680's stand off the wall more than th 580's so even this can help.
