I'm will be going from a geforce 9500 GT 1gb to a radeon hd 4670 in a few days when it comes in. I know I'm supposed to remove the drivers, then use safe mode to remove the display drivers for nvidia, and the physx drivers too(i guess). Does anyone have any specific instructions so I don't cause problems. Worse comes to worse I'd just do a clean install of windows, but I'd rather make this quick and simple. I'm guessing this will remove the 700mb nvidia folder under my c drive. Also, I know you shouldn't touch the nvidia chipset drivers, but out of curiosity, my motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E16813131376 says ATI Radeon 3000 under video chipset. Does that mean I will need the nvidia chipset after I put in the 4670. Thoughts, comments.......?
