Ok im currently using a EVGA Geforce 9800GTX 1gb+ and gonna be swapping to an AMD 6850 or 6870
what do i gotta do in terms of changing drivers/installation order?
i was told
first uninstall the nvidia drivers via control panel/device manager
then remove nvidia card
then install amd card
then download new drivers
this sound right?
No you should prepare everything first so download the drivers and put them (Save to desktop) on the desktop ready for when you re boot.
Some people swear by running Driver sweeper or some such in safe mode when you reboot to be sure all the Nvidia stuff has been removed completely.
Apart from that it sounds about right
