I've just bought a GTX680 to replace my 480 and need some advice on drivers to grab to get the best out of Skyrim.

Going to the betas section at Nvidia's drivers page I have two options available for download (running Win 7 64-bit):
GeForce 301.24 drivers
or
GeForce R300 Driver for GeForce GTX 680

Which ones should I go with? And what are the R300 driver? What makes them different from say the 301.24's?

I am using the 301.34 from the 690 section with no issues.

Yeah, I'm running the 301.24's now with my GTX480, so I figured I'd run them again with the 680. But I was wondering what these R300 drivers are, I don't remember seeing any R300 drivers when searching for updates for my GTX480.

And congrats on the 690. Those things are hard to find. I tried to get one, but could find none, so I finally gave up and bought the 680.
