Recently AMD pushed HD 4xxx drivers to "Legacy" version of their Catalyst driver package. New version of Catalyst that is required for HD 6xxx no longer has those drivers.
Now I can install legacy version and have HD 4xxx working or install normal version and have HD 6xxx working.
They both worked happily with older version of normal driver package.
Am I supposed to use outdated driver for HD 6xxx just to have HD 4xxx working as well?
