AMD Radeon HD 6770M 1024 MB Graphics Driver

I am running a AMD Radeon HD 6770M 1024 MB Graphics Driver and I have downloaded the Adobe CC. I open up Photoshop and says that my graphics driver is not up to date and I should update it. I was wondering if anyone else has had this problem? My computer becomes quite slow and freezes up. I have checked the space on my hard drive and I barely have anything on here. Any advice would be appreciated.
