Why are you still using Mavericks?

To try and get half decent performance from my refurbished GTX 680.
Turns out it's also slower than a 5770 there as well.

Looks like w/e update Apple did broke the Web Drivers, again, for Mavericks. Anyone have any idea when Nvidia should roll out a fix for this?
I a few days new drivers for Mavericks and Mountain Lion will be released. If you want better performance try Mountain Lion.
How do you know? Any idea if an El Cap web driver will finally be released at the same time?
