I want to know the safe and proper way to update the chipset driver..i updated my chipset for my 890gx motherboard from the amd site, during the install i clicked custom n it showed that a northbridge filter and usb filter drive can be installed...should i uninstall my old drivers b4 updating or will it be fine to just install over them. Since the ati catalyst does not have a southbridge driver package in it. How do i properly update my chipset driver? should i uninstall my catalyst for my gpu when 11.9 comes out then update my chipset driver , following a install of the new ati catalyst?
