cleaning my graphics drivers?

[mnewxcv]

getting an nvidia card, how can i clean my graphics drivers and leave my chipset(ati.amd 690g) drivers intact? do I need CCC for the chipset?

also another question i figured id ask here:

if i have an ati car with the latest drivers, and buy a new ati card, can i just pop it in, or should i clean and reinstall drivers anyway?

Uninstall ati video drivers from control panel and reboot windows into safe mode, then run Guru3d driver Sweeper and select to remove ati video drivers only
