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).
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.
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

1I recommend you to remove all and re-install:
sudo apt-get purge bumblebee* nvidia*Then install:sudo apt-get install nvidia-331 nvidia-settings nvidia-prime– guyrombApr 17, 2015 at 13:55 -
Also go to settings -> Software & Updates -> Additonal drivers -> Choose "using nvidia binary driver ... (prop, tested)"– guyrombApr 17, 2015 at 13:58
