I just got a new 7800GS and I want to be sure that everything is good and ready to go before installing. I heard there was some nice free program that gets rid of all video drivers and sometimes just going through windows dosent get rid of them all. I also want to know if i should reninstall windows to make things faster? I just want to know some steps to take before plugging it in basically. I currently have an ati 9250 in there.
