Nvidia expects a lot from it
"WE KNOW that Nvidia plans to introduce a new driver very soon. The company is testing the 75.90 beta driver right now."
If you are a nice boy and if Nvidia likes you there are no problems getting this early version of the driver but if you are not, all that you have to do is wait for the official release like the rest of us. [I take it you are a naughty boy, Fudo? Ed.]
Series 75 is supposed to speed things up but we don't know what performance increases to expect from it.
So we should all hold our breath and wait for this driver that might change a thing or two. µ
