Error rendering with NVIDIA

Hi folks

I have problem when rendering.

Have this error:

The installed version of the NVIDIA graphics driver has know issues.
Please update to the latest driver version.

NVIDIA GeForce GTX 260
Installed: 341.96
Recommended: 378.92

The drivers for my GeForce are only to 342 version.

I need a better graphic card?
Could someone tell me what version of GeForce I would need for that driver version?

Thanks for you help
