Take just one and try this so you can compare. Set BOINC to receive no new tasks. If you're still using an app_info file finish all the tasks you have in your cache first and delete any CPU tasks that are left when the GPU tasks finish. Use a separate WCG profile for that machine and set it to receive/run no CPU tasks.
Upgrade your BOINC client to 7.0.56 After it starts just shut it down for now.
Copy and paste the text below into notepad. Rename it app_config.xml and place it into the WCG project folder. (That will give you 36 GPU tasks each using 1/3 of a CPU core) Delete the app-info file or at least remove it from the folder. Restart BOINC. Set you cache to 0.50 days to get started. Set BOINC to allow new tasks.
Let Boinc download maybe 100 tasks, set Boinc to receive no more tasks and suspend the ones you have(Including the ones that are running) from the tasks page not the project page. The easiest way to do that is highlight the first task, scroll down to the bottom hold down the shift key and highlight the last one. That should highlight them all then click suspend. Now highlight the first task only and click resume. Every time you see the percentage done start to move highlight and resume the next task. Do this until you have all 36 running. It will take a while but this will keep you tasks spread out for better efficiency. Once you get 36 running mass resume the rest and up your cache to whatever you'd like. Your hexcores should be able to knock out 36 tasks in 25-30 minutes, maybe less. (for a reference my 7970 does 24 tasks every 20 minutes on a 2600k running @ 4.2 GHz. with the GPU @ 115 core clock) Depends on your hardware and any overclocks you might be running. Most 7970s can run @ 1125 core clock on stock voltage. With a GPU configuration only I think you should see 1.3-1.5 mill WCG PPD on that cruncher.

Holy crap. 36 simultaneous tasks???? Please forgive my ignorance. I have zero time for playing/reading/learning....for at least a month now....and probably not for another month. I am not familiar with EtaCarinae's systems. Would you recommend this same app_config for a 990x with a 7970? (cpu is at 173 x 25 = 4325, gpu core seems stable at 1240)
