I have an application installed which can make use of my CUDA graphics card, but I'm not sure if I have it configured correctly. Is there a way to check the graphics card activity (throughput, power draw, anything which will tell me if it is being utilised)?

Are you using the proprietary nvidia drivers (otherwise CUDA doesn't work anyway, I think)? If so, you can run the nvidia-smi command in a terminal:

nvidia-smi -a

This gives you – among other infos – the GPU utilization in %.
