OK, but how does it look on the screen? they have put a lot of new features into these cards like Dynamic Super Resolution, letting a 1080 monitor show 4k quality images, Multi-Frame-Sampled Anti-aliasing (MFAA) which allows a much faster alternative to MSAA with a final result that looks just as good, Voxel Global Illumination which will allow dynamic lighting, and VR Direct to support OC Rift and other vr hardware (I hope they (oculous) change the hardware that rift uses to be comfortable to use).
The VXGI in particular looks most promising as it will free up game designers to create dynamic light sources and the objects in the game can be assigned properties that determine how they’ll reflect or absorb the light cast upon them. With this technology, the game programmer can simply place light sources, and those lights will react dynamically to any changes in the environment. Result: more things will be able to be destroyed in a game easier.
When it's all said and done, you buy a card for how well it performs and a huge part of GPU performance is the quality of the rendered images.
