I just recently installed a video card it is a NVIDIA GeForce GTX 960I read the question and answers for graphics cards it stated that it did not run regular SETI work units or Astropulse.However I have AMD 8 core FX processor and it runs eight SETI work units including the AstropulseWork units and one cuda work unit in my work unit results about 90% of my cuda 32 work units are marked as invalid the other cuda 42,50, and Astropulse cudaWork units don't seem to have any problems I was wondering if anybody had any information or answers for me below is a list of my drivers for my display And my cc_config.xml file Below. Any help figuring this out would be helpful and appreciated.
My last question is I was under the impression that I would be running a cuda work unit per core on the video card but it is just running one work unit?

OK, you've got a similar set up to one of my crunchers, so:
I've found that the FX8xxx series of processors support GPUs far better when you limit the number of CPU cores to at least one less than the number that are there, so reduce the % of CPU to say 75%, this will have the effect of freeing up two cores, which will be more than made up for by the increase in performance of your GTX960.
I too had problems when running the very low CUDA versions, the 9xx family of processors don't appear to support very CUDA versions as well as they might.
To fully overcome this you need to run optimised apps, such as those from Lunatics, and only select the CUDA5(0) version for installation.
Another thing, learnt by bitter expirience is turn OFF driver updates in your Windows Update options - the MS drivers really are not up to the mark, so ONLY use the drivers you get from Nvidia, and wait a few weeks after they launch a new one as there have been one or two "duff" releases.

Someone else can talk you through a much simpler way of managing your system, I' away from my crunchers just now otherwise I would post the setting I use.

Jason answered this question in regards to gvtc 970s with new Nividia drivers. They seem to think the newer drivers break cuda 32. They are stating to use cuda 50 only. Install lunatics and go for the cuda 5.x option.
