Welcome aboard Clayton!
On the Bio-Medical side of things your pretty much limited to running GPU Grid if you want a project that will use your GPU. Everything else is CPU. For now at least. There are a few projects that are waking up and realizing that utilizing a GPU will get more work done for their projects. Poem will probably be the next to offer work for GPU's. Poem actually had a GPU application before this but it had issues and they stopped using it and went back to the drawing board to start over again.
For CPU Bio-Medical related projects I recommend Poem, Simap, Docking, Rosetta, Malaria Control, Mind Modeling, and WCG has some projects that deal with Bio Med issues. Namely Mapping Cancer Markers and FightAIDS@Home. Intermittently they also run Help Fight Childhood Cancer and a few others.
On the Physical Sciences side of things there are some projects that will put your GPU to use. I know Asteroids, Seti, Milky Way, and some others have GPU applications.
