Setting max_concurrent to 8, leaving gpu_usage at .33 and setting cpu_usage to 1 should get you 3 GPU tasks running and leave the other 5 threads for whatever else you want to run. Like Snow Crash said you may have to shut down and restart boinc twice for the app_config to start. I had that happen to me a couple of times. First time it did I thought something was wrong with the config file.
This has not been my experience. I have only the gpu app config info and its specced to use two cpu cores for the gpu. Boinc set 100% of cpu cores will then fill the remaining two cores with whatever cpu projects i have enabled.
