I am still using the 9## series (GTX 980) and as of Monday, 15 Aug 2016 the latest release is 372.54. Be advised that there is now an option for Windows 10 32-bit, and 64-bit (has been for a year), but also Windows 10 Anniversary 32-bit, and 64-bit. These drivers should be considered as mutually exclusive, so make sure you make the right choice.
If you are a VR user it is recommended that you read the notes under "Limitations in This Release" for the driver of your choosing, as well as Fixed Issues for the version in question (specific to Steam VR), and under OS specific issues such as "Windows 10 Issues."
Windows 7 is still the only version of Windows that does not suffer the random SLI/UEFI error 14 bug.
