Having gotten my windows7 pc out of storage and back up and running, have had to add some more exclusions to the cc_config.xml for all the new open-cl apps, I missed one from Einstein and it completed. Process Explorer showed that it was using only 2% - 4% of the CPU and 37% - 47% of the GPU. The GPU that it ran and completed on is an integrated AMD HD3000. The task should have failed, but didn't.

And your question is what, exactly?
If you feel that work on a project science application shouldn't have run to completion or is otherwise wrong, you really have to tell the project about this. BOINC is only the managing program, it doesn't do any of the calculations.

A GPU task only uses a small amount of the CPU for overhead, as expressed by the BOINC manager readout "Running (0.XX CPU + 1 ATI GPU)" when crunching a GPU unit. Otherwise, the rest of that CPU core can be used for regular CPU work. As for the low utilization of the GPU, you'd best ask at the project with which you are experiencing this behavior.

That's assuming you are looking at the correct task in the process manager; make sure you're viewing all users.
