The answer above sudo apt-add-repository ppa:graphics-drivers/ppa today results with:
Fresh drivers from upstream, currently shipping Nvidia.
## Current Status
We currently recommend: `nvidia-367`, Nvidia's current long lived branch.
For GeForce 8 and 9 series GPUs use `nvidia-340`
For GeForce 6 and 7 series GPUs use `nvidia-304`
nvidia-370 is the current BETA release!
## What we're working on right now:
- Normal driver updates
- Investigating how to bring this goodness to distro on a cadence.
## WARNINGS:
This PPA is currently in testing, you should be experienced with packaging before you dive in here. Give us a few days to sort out the kinks.
Volunteers welcome! See also: https://github.com/mamarley/nvidia-graphics-drivers/
### How you can help:
## Install PTS and benchmark your gear:
sudo apt-get install phoronix-test-suite
Run the benchmark:
phoronix-test-suite default-benchmark openarena xonotic tesseract gputest unigine-valley
and then say yes when it asks you to submit your results to openbechmarking.org. Then grab a cup of coffee, it takes a bit for the benchmarks to run. Depending on the version of Ubuntu you're using it might preferable for you to grabs PTS from upstream directly: http://www.phoronix-test-suite.com/?k=downloads
## Share your results with the community:
Post a link to your results (or any other feedback to): https://launchpad.net/~graphics-drivers-testers
Remember to rerun and resubmit the benchmarks after driver upgrades, this will allow us to gather a bunch of data on performance that we can share with everybody.
If you run into old documentation referring to other PPAs, you can help us by consolidating references to this PPA.
If someone wants to go ahead and start prototyping on `software-properties-gtk` on what the GUI should look like, please start hacking!

Be advised there are instructions on Nvidia site about disadvantages of upgrading Debian (which Ubuntu is based on) versus clean install.
Also be advised Nvidia website might have special instructions for Haswell, however their current drivers use the same one from my lowly GT650M up to OP's GT760M but there can be all kinds of recommended changes in other areas of the system based on Intel CPU and/or systemd or Debian.
Also there are special circumstances like the OP where Integrated Graphics and Discrete Graphics aka "Hybrid Graphics" are built into the Motherboard.
The Nvidia website does talk about black screens that are common questions in A.U. (Ask Ubuntu) so it's a worthwhile visit for most reading the OP's question.

Given than you installed the drivers using the additional drivers tab, you should have already installed Nvidia Settings. Look in there for the PRIME Profiles menu and use it to switch between the two cards as shown in the image:
Alternatively, you can open your terminal and write the command
to check which of the cards is your system using, and the commands
or
to change between the two cards and then restart the session.
