Which driver is up to date with my 8600gt? The one on Nvidia driver one or the one on windows updates? Based on the dates it seems like the one on Nvidia driver download page is up more to date since the date is 2009 compared to 2007 on windows updates. The thing is why does windows update show the old driver update, when i installed a newer one on nvidia site. Heres a pic of both of them. So which one exactly is the newer driver for my nvidia 8600gt.
