Having exactly the same issue.
Unfortunately, Zotac does not have newer bios available and switching Nvidia drivers does not change a thing. Currently using the latest beta 285.79.
However, one thing *did* seem to make a difference. Using MSI Afterburner I sometimes underclock the GPU for about 50MHz and the game seem to run for longer without crashing.
Looking at the GPU usage after the game crashes does not show that the GPU was overheated or overutilized which makes the drivers (or bios) suspicious.
