If your system is running fine do not update!. If you want to update create a System Restore Point firstUnpack/decompress the downloaded driver package with Winzip or WinrarUpdate drivers manually or delete the driver folders you don't want to install and use the setup.exe
This ethernet driver is older (3.4.3) against that one in 3.13 package (3.6.3), also there are some Jedi files for 9x platform (probably some Jedi game definitions to fix some compatibility issues), IDE is also older one. Gart seems to be newer (3.4.3 versus 3.3.4) SMB differs only by number (inf file is same as 334) catalog file for both are missing, so pure beta so i'm going to test that new nv_agp.sys :)
