The GTX 760 and GTX 770 performance with Nouveau is virtually identical due to both GPUs running at the same frequency with the open-source driver. All of the Nouveau results are far behind the binary NVIDIA 334.21 Linux graphics driver due to the aforementioned re-clocking problems for Nouveau/
Besides the performance being slow, Nouveau didn't work on the GeForce GTX 780 Ti and there is not yet any public "Maxwell" GPU support outside of using the binary blob.
