What sort of gpu?  Nvidia and AMD tend to be quite different.

Nvidia tends to use Cuda framework, AMD uses OpenCL.  They offer some level of compatibility I think, but nothing I've particularly used outside of pure  graphic opengl for gaming and desktop compositing mostly.  Each tends to be better at certain uses as well depending on the type of functions invoked in their process engines.

Using AMD with bitcoin mining for a bit, you had to install opencl libs under ubuntu, bind the app at the socket level to the gpu, and not do anything to the system that needed much graphic use beside that.  Blender or Hugin if using GPU, probably much the same.  Nvidia will have a cuda equivalent.  The googles are your friend for your particular case to get the appropriate libraries there.

I'd recommend using a window manager that doesn't composite if they peg your gpu.  Install psensor and watch your gpu temps to see how much they're scorching it.  Powertop would be fun to watch as well when in use, running a bitcoin miner on mine caused it to go into furnace mode.
