Hermione in Gryffindor?

The sorting hat placed Hermione in Gryffindor even though she, as 
Sirius put it, is the smartest witch of her age.

Ravenclaw is for the bright ones and Hufflepuff will teach those of 
muggle parentage. 

My question is: She is exceptionally bright. Since she's in 
Gryffindor does that mean that she will perform feats of 
extraordinary bravery? Or did that hat just let her choose her house 
out of the three choices she had? (like Harry chose.)
