Q: if i get a faster CPU will programs use a smaller percentage of my cpu or will they just run faster?

For instance, on OSXAbleton and VLC are using about 40% of my CPU each according to System Monitor. If I got a brand new machine would they use a lower percentage freeing up my cpu like adding more ram gives more memory overhead or does it not work that way? How does it work?
