Octane only can select 1 gpu

I have two GPUs in my system, a GTX 780Ti and a Quadro K2200. However, Octane only allows me to select the 780 Ti? 
I'm not sure that the student version of Octane supports Maxwell GPUs yet. You will have to wait for the new version to come out, which I think will be after 3.0 is finished.
