Yes that’s right and especially if you play Starcraft II beta.
You can find further info on this issue here.
The conclusion is that if you upgrade to the latest driver(196.75) and run the right graphics intense game your graphics card fans might start to malfunction because of some probably(very) stupid piece of code in the new driver and thus your graphics card will start to overheat, leading to irrevocably damage to your card, most probably killing it for good.
These being said, DO NOT UPGRADE to the latest Nvidia 196.75 driver!
If you have done already then roll back to the last version. Nvidia has also taken action and removed the download for the driver in question, but be aware since you might get that driver through Windows update or any other third party drivers and utilities software upgrade tool you might have on your system, like the ones that come from laptop vendors for eg.
