Ok, so now I have a few rigs crunching.  Having put my first multi-gpu rig online I now want to make sure  I'm getting all I can out my rigs. 
 
I found the thread here https://forums.evga.com/BOINC-app_configxml-file-settings-for-GPU-Projects-m2213432.aspx specifically about [link=mailto:seti@home]seti@home[/link] which is what I'm crunching on.  The thread was a bit old, but is the app_config still valid (yes, I know i need to change it from v7 to v8 lol)?
 
Also, I have read a few different places about using cpus to back the gpus.  Now comming from folding that simply means i need to keep a full core/thread for each gpu.  Is that what they're all referring to?
 
The thing I've probably read the most is "it depends" in reference to how to optimize, but never on what it depends.

    Yes the app name must match to a current application from seti.
     
    In the boinc manager the gpu application will state what it's using. Below is typical.

    As you can see I'm leaving a core open because GPURID is telling me it's using 0.986 cores of the cpu. So I'm running 3 of 4 cores on SRBase. Often it doesn't use as much as it says but playing it safe. You can tweak it even more with app_configs but that is really trial and error. bcav is the best trial and error guy here.

    Ok I think i had the settings backwards.  If I want to use more of my cpu's power I should set it closer to 1.  Thanks a bunch

    You can find a lot of app_config.xml Files here.
    https://forums.evga.com/search?searchid=1344403&phrase=app_config.xml&high=app_config.xml
    Do not Create the Folder and create the app_config.xml add the Project from BAM! or without and after the Client has been added then create the app_config.xml file.
    Not everyone uses BAM! I use it myself.
    Each app_config.xml is different like this is what I use for http://www.enigmaathome.net/
    This Project uses 1 Full Thread or Core so <cpu_usage>1.0</cpu_usage> setting is not really needed but I set it mine
    This Setting <gpu_usage>0.5</gpu_usage> will run 2 Tasks on Each GPU on the Host
     
    ProgramData\BOINC\projects\www.enigmaathome.net 
    <app_config>
       <app>
         <name>enigma_cuda</name>
         <gpu_versions>
             <gpu_usage>0.5</gpu_usage>
             <cpu_usage>1.0</cpu_usage>
         </gpu_versions>
       </app>
    </app_config>
     
    Under (Drive):\ProgramData\BOINC\
    Create a file called cc_config.xml and put the below in
     
    <cc_config>
     <options>
     <report_results_immediately>1</report_results_immediately>
     </options>
    </cc_config>
     
    The rest can be removed from this file
    Other app_config.xml I use
     
     ProgramData\BOINC\projects\boinc.thesonntags.com_collatz
    <app_config>
       <app>
       <name>collatz_sieve</name>
         <gpu_versions>
             <gpu_usage>0.5</gpu_usage>
             <cpu_usage>0.1</cpu_usage>
         </gpu_versions>
       </app>
    </app_config>
     
    This is Heavy CPU Project that uses the GPU but very little and you can run as many Threads that your CPU has.
