Pretty big news today as many of you will be effected. Nvidia is going to halt driver support on older model GeForce Graphic cards. Basically and roughly up-to the 200 series will get an driver EOL, meaning that basically the Geforce 8 Series, 9 Series, 1xx series, 2xx series, 3xx series and Geforce 405 from the 4xx series will not be supported anymore.
The Release 340 drivers will continue to support these products until April 1, 2016, and the NVIDIA support team will continue to address driver issues for these products in driver branches up to and including Release 340. However, future driver enhancements and optimizations in driver releases after Release 340 will not support these products. R343, will drop support for the older DirectX 10 generation.
Have a peek here to see what card are effected on long term (2016).
