Nick,
With Autocad, the majority of number crunching is done in system memory but the display crunching is done on the display card. Weak video cards show up as slow zooms, stuttering video when moving, slow regens, inaccurate placement of objects (when not using object snap), odd looking curves and circles, incomplete fonts and other display related anomalies. None of these things will affect the printed output except the object placement. These are the kinds of things that are annoying to power users but can be acceptable to someone who is using the software infrequently or in a non-production environment. If you follow the Autocad guides to hardware/drivers linked above, you should have no problems.
