I do not know where to ask this question, but my new P55 gd65 mobo with Intel i7 860 lga 1156 cpu which is running 8 threads, has a gpu card. From the preference menu, I checked the box which allow use of gpu while computer is in use. However I do not know if it is working or is allowed with Rosetta projects.
Many thanks for your answer or comment.

I turned off my 5computers when I went on vacation. When I return today, I can not upload work. Need work units to run computers.

To answer the question posed in your subject line, yes, GPU programs run in tandem with code on the CPU. But no, Rosetta@home does not have a GPU enabled application available at this time.

Yes. But it gets shady when you have more than a few GPU's running at the same time. I think the rule of thumb is one CPU core for every two GPU cores. Correct me if I'm wrong.

But Rosetta@Home doesn't have a GPU client.

I have run a gpu in a machine with a single core cpu and not had any problems, so it may depend on the project. The new ATI software for the video card, only uses 0.05% of the cpu when the gpu is crunching.

But Rosetta@Home doesn't have a GPU client.

And yes you are correct, Rosetta does not have a gpu version.
