Hello, I had an old radeon HD4850 but recently I changed it with a new card HD 6950. I uninstalled every driver, changed the card and installed the new ones, but I noticed that the file that I downloaded has installed the catalyst control center instead of the vision engine control center. It is strange because my CPU is an AMD too (a phenom II X4), and I'm pretty sure that I had the vision engine with the old card. How can I have it? Thanks.
