Destroying Actors for Optimization

CORE Game

Hello guys,
I was wondering is it important to destroy the actor when it goes out of the scene, for example if iam shooting bullets and they go out of the iphone scene out of the (320x480) area, is it important to destroy it so i make some space in the memory?

That or you can interpolate or move it to an x y position on the screen i.e. like under your spaceship

well my point is to optimize the game for better performance, like every spawned actor requires an end ? or they will stack and make the game slower.
