Although the GeForce GTX 970 and GeForce GTX 980 were launched in late 2014 and the GeForce GTX 980 Ti and GeForce GTX 960 in early 2015. But NVIDIA considers that these graphics cards are the stuff of the past and for proof full series of GeForce GTX 900 (TITAN X, Ti 980, 980, 970, 960, 950 and mobile versions) has become part of the legacy drivers family.

Legacy drivers means that NVIDIA abandoned support for these graphics cards, although there is no official announcement has been made till now. It is logical to think that GeForce GTX 900 series graphics card owners will receive limited support of driver to fix problems for at least a couple of years, but you should not expect any improvement in performance or better support for upcoming games on the market.
Thus NVIDIA will focus its efforts from now on the GeForce GTX 1000 series under the Pascal architecture, hoping to provide enhanced graphics performance under the Vulkan and DirectX 12 API where we have already seen that the GeForce GTX 900 series has not performed very well. We are still waiting for the official details from NVIDIA camp.
