does it show the GPUs in the list once it starts running?

it should show all the possible mining targets that it is setup for, so if you had 2 gpus it should show those on the list (in my experience anyway).

I had an issue where I had to rerun the aticonfig command once I added more GPUs or it would not recognize them.  Mine does not allow me to mine on the CPU however, so I don't know any more than that currently
