I'm running them and it seems to be ok....What exactly is it killing?
UPDATE: Apparently this driver affects the fan speed control causing the GPU to overheat. If you use a program such as Riva tuner to utilize fan profiles, you are probably ok. I have the 196.75 drivers on my 8800GTx2 SLI and 8800GTX OC and neither have had temperature issues since I use Riva tuner to directly control the fan speeds.
If you are unsure about your gpu temps, I would roll back to the previous driver.
