For fun I ran an cudaHashcat benchmark-

Code:
Device #1: GeForce GTX 980M, 8191MB, 1126Mhz, 12MCU
Device #2: GeForce GTX 980M, 8191MB, 1126Mhz, 12MCU

Hashtype: MD4
Workload: 1024 loops, 256 accel

Speed.GPU.#1.: 15339.6 MH/s
Speed.GPU.#2.: 15379.7 MH/s
Speed.GPU.#*.: 30719.3 MH/s

Hashtype: MD5
Workload: 1024 loops, 256 accel

Speed.GPU.#1.:  7324.5 MH/s
Speed.GPU.#2.:  7348.8 MH/s
Speed.GPU.#*.: 14673.4 MH/s

Here is a sort of condensed version that I used...

I'm using: kali-linux-2.0-amd64 with NVIDIA-Linux-86_64-352.63

Update and Upgrade
Code:
apt-get update
Code:
apt-get dist-upgrade
Code:
apt-get install -y linux-headers-$(uname-r)
Download latest NVIDIA driver
http://www.nvidia.com/download/index.aspx

Move to terminal with CTRL+ALT+F1

Purge old drivers
Code:
apt-get remove nvidia-kernel-dkms
Code:
apt-get remove nvidia-* --purge
Code:
apt-get remove nvidia* --purge
Move to downloads folder
Code:
cd /root/Downloads
Make executable
Code:
chmod +x <Your NVIDIA file name>
Stop gdm3
Code:
service gdm3 stop
Run the NVIDIA setup
Code:
./<Your NVIDIA file name> -a
Ignore warning about 32bit stuff

Accept xconfig notice

Start gdm3 and return to GUI
Code:
service gdm3 start
Create blacklist file
Code:
nano /etc/modeprob.d/nvidia-installer-disable-nouveau.conf
Add the following
Code:
blacklist nouveau
options nouveau modeset=0
options nouveau.modeset=0
Final updates
Code:
apt-get update && apt-get upgrade

NOTE: This was all learned following sihag's tutorial and all props go to him. I am not responsible for any issues or typos but will correct them as I learn about them
followed the steps and X11 log says: No screen found. Any ideas?
