ok i have a dell 8600 with nvidia 5650. ive updated the drivers several times from the nvidia site. i have the forceware 53.03 now. should i also update the video driver available on the dell site or its not neccesary. i have the v4.31 in the bios right now. the dell site says the new ones r v6.14. also does it make much of a differnce if i completely uninstall the older drivers before installing the new ones. thanks
