I've actually been reading some of the nVidia forums and there has been a bit of mentioning of the GTX 560 Ti Cards (I'm one of them). It seems to be sporadic and fairly spread out among the different manufacturers that the Fermi based cards are a bit flawed to a degree. While the more up to date drivers seem to be the culprit, there have been some reports about the 560 Ti cards still having the problem.
I'm one of the people having the problem after running the card for several days which suggests it has some resource issues after a while. Some people also have linked the issue to running either IE or Firefox as both are GPU enabled browsers and seem to cause some problems as wel.
