I found a bug here the way that tasks are assigned to the GPU with the nvidia. I have:
Seti@home (GPU enable)
rosetta@home
Lattice
malariacontro.net
GPUGRID
project. What I have seen today. My computer finished a task with GPUGrid @ about 11:15pst.
The clients moved onto the Seti GPU tasks here running about 5-7 minutes a tasks. What did not happen is after about an hour. The GPU tasks did not swtich back to the GPUGrid task. It keep processing smaller Seti tasks one after another for 6 hours.
This will cause the GPUNet to time out.

I was able to force the GPUGrid units to run by pause the Seti Project and letting GPUGrid get the GPU open processing slot.

I too am experiencing this. Ever since Seti & Beta(cuda) , was lanuched I have failed alot of GPUGrid WU becuase Seti would not allow GPUGrid to run. They will both seti's will let each other run, but not GPUGrid.
GPUGrid has an high resource allocation, but that does not help. And the Seti WU's have a longer deadline than GPUGrid.

The current design of BOINC doesn't differentiate between gpu and cpu resource allocation, in fact it doesn't even have a gpu resource allocation. It uses the cpu time to work out resource share.

There is discussion underway to allow work-fetch differentiated by cpu and gpu. The BOINC developers will amend this in a future release. When this new version will be available is anyones guess. Click here to see the proposed changes.
