 I just purchased a XFX 7750 graphics card for a minor upgrade on this pc. I am trying to find step by step of what I should do prior to installing the card. Do I need to uninstall the integrated drivers as well as the CCC in the programs and features area. I was looking for info on these forums but haven't able to find for my particular model. My other posts have been answered thank you but I need to clarify this process. I am not expecting this to go smoothly. Thanks anyone out there.

 I am running Windows 7
