Two new NVIDIA drivers hit the web in the last couple of days, you can download both drivers via NVIDIA's driver download page.
The 344.11 WHQL release adds support for the GeForce GTX 980 and GeForce GTX 970 and promises "the ultimate gaming experience" in Borderlands: The Pre-Sequel, The Evil Within, F1 2014 and Alien: Isolation. This release also adds support for G-SYNC Surround multi-screen setups and fixes a number of bugs described in the full release notes.
NVIDIA also rolled out the GeForce 344.16 beta driver. Unfortunately, we have no idea what's new or fixed in this driver as the company's release note link doesn't work. Rumor has it that this driver fixes a compatibility issue with the new Maxwell GPUs.
