UPDATE: Sorry everyone, I quit the job I was working at and apparently I had this sheet on my google account there. They deleted my account and this sheet went with it -_- sad day... and even though I thought I had backed it up to my other gmail account and made a copy of it, apparently it deleted that too. Way to go, google.
If anyone else out there managed to get a copy of it, please share it!

Update May 20th 2016: Specs from NVidia's new GTX 1080 and 1070 added. Real-world test results to come as soon as cards become available.
Update Jan. 23rd, 2016: Charts added showing updated bang for your buck, power for your buck, best for 3D software viewport performance (max, maya, etc) and GPU render times added. You can find all data at the bottom of the google sheet.
Jan 23rd, 2016 scores:
Bang for your buck (including VRAM): GTX 970
Power for your buck: GTX 970
Best for Display performance: GTX Titan X SC and Quadro M6000
Fastest GPU rendering: GTX Titan Z
Current conclusion: It depends on which software you are using. In 3ds Max, Maya, C4D, Blender and Adobe products, GTX cards are just as fast (and sometimes faster) than their sister Quadro cards depending on your viewport mode (shaded, wireframe, etc). Quadro cards may still have an advantage in some 2D and 3D software (none that I have seen so far but there's still a possibility). Latest GTX cards seem to work well in all viewport modes.
Note: Quadro cards tend to be faster with OpenGL and GTX cards tend to be faster with DirectX. Most 3D software will allow you to choose between the 2 to get better viewport performance depending on the type of card you have installed. HOWEVER: It's worth noting that some software will loose some functionality by switching to DirectX or OpenGL. Maya, for instance, will loose functionality in hair, fur and a few other things by switching to Direct X. Later GTX cards, however, seem to handle OpenGL quite well.
Note: If you are looking for the very best viewport performance and aren't on a tight budget, consider buying multiple high-end Quadro cards and then SLI them together for better viewport performance. BUT BE AWARE: this does not work in all machines! And it only works with certain Quadro cards. You can see a list of compatible cards and machines here: https://www.nvidia.com/object/quadro_sli_compatible_systems.html
I will be updating this chart as soon as new cards are released.
