Best Nvidia drivers?

[Alientank]

I have my 6800 GT @ Ultra speeds right now and it's rock solid stable, I installed the 66.70's and I notice frame rate drops and the game has locked up and complained about my display driver (bsod) and I had to restart. It just happened again. What are the best drivers to use in your opinions for the game?

I'm using 66.81 on a 5600 Ultra and it's running pretty well.

61.77's I'm using, seems to be working good now. I had that desktop crash thing but it seems to be the plague of all cards right now and all machines. anyways yes we have the same card. OC'd GT
