C++ pointer vs. non-pointer

Sup /prog/

C++, if I make my own class, lets just say class cShitHead

cShitHead dave * new cShitHead( "dave" );
dave->PrintName();

or

cShitHead dave( "dave" );
dave.PrintName();

I myself like the pointer notation better. However, which one is more efficient and better on memory? and why?

it's 2010, most people are still stuck with a 4GB RAM limit. until machines with 6GB of RAM cost less than $50, every last bit will still be precious.
