I know there is alot of talk about overclocking the NVIDIA gpu, but what about underclocking? I want to save battery but without the reboot . I am toying with nTune, and it begs the question: How low can I go while still being able to do basic things such as using Word or web browsing?

The card has 3 clocks: 2D, 3D Low Power and 3D Performance.
During normal use, like web browsing and office applications, the 2D clocks are used, which are: (Core/Memory/Shader)
which are pretty low compared to 3D Performance, which has the clocks:
However, if you think to underclock it even more, these are the clocks CPU-Z tells me when my card "fails" (by fails, I mean the computer has faced "something" that the computer needs to be rebooted for the GPU to use the 3D Performance clocks):
But keep in mind that even the RAM starts to fail when DRAM freq goes down to 133 Mhz, so these might be the minimum clocks.
