Started to look into this, especially since many high quality games are using it and keeping a high FPS. I was wonder if someone could head me in a good direction for this. Also, what speed loss am I looking at by using it?

"Bump mapping" these days is called "normal mapping" or possibly (if you're adventurous) "parallax mapping".

The speed loss is anything from 0 to 30%, depending on where you are currently constrained. If you're CPU bound, the extra shading work will be "free" because the GPU would just sit idle otherwise anyway.
