I used to be able to switch to Nvidia by going to software sources. Now when I click the driver for my graphics card it downloads, turns green and it looks like its using the correct driver but when I go to system details it says its using my Intel graphics. The performance is accordingly average... But I have gfx card with 2G of dedicated memory! Is there a way I can do this? Possibly something in grub? Or even better: graphics card switching without need for reboot? Something like: https://gfx.io/?

If you have nvidia prime installed just go to nvidia x server settings and choose it in prime profile (you need to relog to apply the changes). Nvidia prime

To install prime:

First make sure bumblebee not installed! Or just remove it:

sudo apt-get purge bumblebee*

Install:

sudo apt-get install nvidia-prime

You can also install prime-indicator for easier switching. Prime indicator

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install prime-indicator

If you prefer to use bumblebee/have it installed you have to run the application with a command to use the video card (advantage: you don't need to relog).

optirun <program-name>

To install bumblebee make sure you remove prime! More info: https://wiki.ubuntu.com/Bumblebee
