Particles might be an option - another is dupliverts, which is about 
having an object (e.g. a pyramid mesh) show in the location of each 
vertex of a mesh: 
http://wiki.blender.org/index.php/Doc:Manual/Modeling/Objects/Duplication/DupliVerts 
. Dupliverts is much more efficient for the scene handling (is just one 
object) and for drawing too (at least it could be, and i hope it is 
somewhat in reality of the current code now too .. dunno if it has been 
optimized to VBOs or anything like that yet).

50k objects in a scene is a lot for Blender currently, it is not really 
optimized for that (could perhaps be improved, dunno if have been looked 
at recently).
