You see I was always confused with this. I just went to nvidia.com and downloaded the newest driver for my card, and within the hints it says that you should uninstall every other nvidia display driver before installing the new one. So I uninstalled them, downloaded the new driver, and installed the new one, but I'm not sure where I would go to make totally sure that I have the newest up to date one. Run -- dxdiag, seems good, but the date in the drivers column of the display isn't the same date as the release date of the driver on the nvidia website . . .?
