No CUDA for Ubuntu users?

I’ve been running Ubuntu for a year now on a dual boot Win7 Ubuntu system. I’ve always used Ubuntu to run Blender because it was supposed to be faster than windows. When I installed the newest 2.63a release I tried a benchmark test between Windows 7 and Ubuntu and found that Windows was much faster. After looking into it It seems that there are more politics involved than performance as Nvidia (I have a Nvidia GeForce GTX 560 Ti card) won’t release their CUDA code to the open source world…the bastards.

Is there anyone that knows more about a easy to install driver for Nvidia users or a solution?

Ubuntu?
Just click yes, yes and yes when it tells you there’s a new proprietary driver available, or install it yourself in the hardware thingy. Just a few clicks.
