I have a question about drivers, should I use the ones, provided by ubuntu(14.04 - 331.38), or should I install the latest ones from nvidia(331.79)? which would work better? Nvidia page says this:
Note that many Linux distributions provide their own packages of the NVIDIA Linux Graphics Driver in the distribution's native package management format. This may interact better with the rest of your distribution's framework, and you may want to use this rather than NVIDIA's official package.
So, I'm kind of scared to try that since I had bad experience with installing the latest AMD Radeon drivers before. I know, it's not the same but still...
And if I should choose 331.38 which one of that? 331.38 - updates what difference is between this and 331.38
