I see that siac is back in the Sia folder...

When I run the following command in command line
siac miner status

I get the info for CPU mining.

I was wondering if there was another similar command for the GPU mining? I want to check and make sure my mining is actually registering/working as it should be.
Still haven't mined a block and I've been going at it pretty strong for a while (1-2 gigahashes/sec).

On another note, anyone know the best mining GPU to use for SIA? (if electricity is not a problem)
