Answer 1

You have a fairly recent video card: go to the NVIDIA website , select the family and type of card, and see which driver they recommend for this card.
Don't trust apt-get too much, there have been cases where the driver from NVIDIA was much better than what was offered from the repositories.

Answer 2

The idea of ​​installing a driver for a video card from the repo is not very good. As already mentioned above - download the latest drivers for this video card and install manually.

Answer 3

Download from offsite and run the installer. There are no problems.
