I am planning on changing my ATI Graphics card to a NVidia one. Just how hard should this be, in terms of driver instalations and that kind of thing. Also if someone could give me a rough list of order to do things in it would very much help. Thanks
Use Drivercleaner Pro (its free) to cmpletely wipe anything todo with ATi drivers off your system then just install teh nvidia drivers Driver cleaner prois aviable @ http://www.drivercleaner.net/
Fr4nk has it spot on, uninstall the old drivers, shut down, replace the card, turn on, install, reboot, run.
