Nothing I added (primarily mri_ca_register and mri_em_register) makes use of multiple GPUs, any more than Freesurfer makes use of multiple cores. I don't know about any additions since. If you have more than one GPU, you can run more than one subject at once (if you point each run to a different GPU). Also, make sure you're using the Fermi binaries on that GTX 480.
