Nvidia just rolled out their latest WHQL certified GeForce drivers for GeForce 6, 7, 8, 9, 100, 200, 300, 400, and 500-series desktop GPUs as well as ION desktop GPUs.
The R275 driver suite is all about performance gains. On 400 and 500 series GPUs in particular there are quite a number of bumps in FPS for Crysis 2, Civilization V, Portal 2, Bulletstorm and Batman Arkham Asylum.
There are also a number of bugs ironed out from the previous beta, thanks to the savvy Nvidia community; see below:

If you’re running GeForce drivers V270.51 or higher then you should have received the update notification via your taskbar, if you have the ‘auto-update’ feature enabled. For everyone else you can download the drivers here.
