Well, there are but they also tend to be on the bad side.
I don't know of any off the top of my head but I am sure you can find some if you like. The thing about modded drivers are, they are harder to keep measurments of temperature and things are tweaked for gaming more often than not. Although this may seem like a boost, I have always heard to be very careful with them.
NVIDIA Drivers are not bad at all, I have never had a problem with them save slight differences in temperature read outs.
Everything else works for the most part (atleast with what I have done), and they have never caused my computer to crash.
In the long run, I would suggest sticking with the generic drivers from NVIDIA.
