Question Is there a way to display polygon count in a model/CUA?

[VRmatt]

Curious if there is a plugin I can apply that will give me a polygon count?
I find that I can download 2 models that are very similar (a coffee cup) and one will have 1mil, while the other is 50 polygons.
I'd like to know what impact the CUA has on my scene.
Thanks!
