so becouse ive had nvidia for 10 years and dont know what im doing with ATI im a dumbass?
It just means you need to be more patient until you get everything working right.
Btw, what windows version do you have? If it's Windows 7, there shouldn't be an issue with your old Nvidia drivers being installed. Win 7 allows for multiple sets of drivers, but if you have Vista, that could very well be your issue.
