NVIDIA has pretty damn impressive driver support when it comes legacy devices. Although we just leaned that NVIDIA will be reducing the number of video cards that they will be continuing to support. NVIDIA stated that after GeForce Release 340 drivers that any subsequent driver release starting with Release 343 will cease to support many older GeForce cards. The list of cards that will now have EOL drivers are listed here.
The NVIDIA GeForce desktop video cards that are most relevant to our readers and are on the way out when it comes to drivers are mainly the older GeForce 8/9 series cards along with some cards in the GeForce 100/200/300/400 series. The GeForce 400 series made it out relatively unscathed as the only card to have EOL drivers is the GeForce 405 and it is doubtful many enthusiasts would even have that.
Even if your card has been marked to be put out to pasture there is nothing to freak out about as the GeForce 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.
