Hey guys, hate to crash the convo here, but I've been having a lot of trouble with cudaminer today.
looks like the known "multi-instance support is broken in CUDA 5.5 with the latest drivers" issue.
As a workaround, try running -d 0 on one cudaminer instance and -d 1 on another instance.
Maybe a driver downgrade to the driver that shipped with the CUDA 5.5 toolkit helps. But then, a 760 card might be "too new" for it to be recognized by this older driver version.

Thanks so much Chrstian, seems to work just fine now when running two seperate instances of cudaminer.
Cheers
