Prior to January 2019, if there is a sudden security incident, such as a flaw, 32-bit N-card users can get emergency security updates, but there will not be any performance optimizations, enhancements, bug fixes, etc. GeForce Experience software also stops at the same time.
At present, in the driver download list on the NVIDIA official website, the 32-bit version has disappeared completely in the operating system options. The 32-bit option on the GeForce.com website is still there, but I believe it will not last long.
For AMD, the R400 series has already given up on 32-bit systems, and the earlier R300 and R200 series are still offering 32-bit drivers.
