I just noticed that N-Body Simulation is only CPU. So I checked the box Use CPU. But then I get both CPU & GPU WUs for Separation. Is there any reason to run both CPU & GPU Separation WUs???
Could another option be added to Preferences/Run only the selected applications:
✔ Milkyway@home N-Body Simulation
Milkyway@home Separation - CPU
✔Milkyway@home Separation - GPU

N-body units ARE cpu units, you need to uncheck them to only get gpu workunits.
My checkboxes look like this here:

Use CPU
Use ATI GPU
Use NVIDIA GPU

Gpu tasks are about 10 times faster at most projects, gpu's have hundreds if not thousands of little tiny cpu's so crunch things much faster if they make the app for them. BUT some projects do not have gpu apps because they say the crunching is not faster because of the way and amount of memory used in the crunching.

This is what I want:
✔ Milkyway@home N-Body Simulation - CPU
Milkyway@home Separation - CPU
✔Milkyway@home Separation - GPU
