Displacement maps are great for adding fine detail with a normal map, and can 
reprisent better detail in some areas that a normal map might not display as 
sharply. Combing these two can create some really solid detail that looks 
natural without adding as dense geomitry and therefore letting you draw in say 
a complex looking architectural design on a side of a wall - bump mapping would 
work in part for this, but with the displace map, and normal mapping, you'd get 
the feel of the geomitry. Displacement does tend to work better with a bit 
higher poly count, but can be a good halfway point to get a little more affect, 
and depth.
