NVIDIA GeForce 700 Series: Stick To The Binary Linux Drivers

Well, that's the current story of the NVIDIA GeForce 700 series on Nouveau at this time with Linux 3.14 and Mesa 10.2. If you are using a GeForce 700 series GPU or plan to buy a new Maxwell GPU, you really will want to either hold off on the purchase or use the binary driver for at least several months. If using the binary NVIDIA Linux graphics driver all of the features (sans overclocking) is there, the performance is on par with Windows, and overall the NVIDIA binary driver is in great shape. That's the short story until there's working and reliable Nouveau re-clocking support "out of the box" and until Maxwell GPU support emerges.
