ok, i just got a BFG nvidia 8800 GT OC. after i put it in and turn on the power the moniter tells me something like "cannot display resolution (optimal resolution 1440*900)". keep in mind i uninstalled the drivers for my previous card, and even updated my moniter driver. my moniter model is a dell S199WFP if that helps anybody. maybe install the nvidia drivers now?? with the ati still in?? aaargh! please help!
