Hi, I have an ATI Radeon HD5670 and I am trying to update my driver, so I went to their site and put in my card model and downloaded the Catalyst Software Suite which includes the Display Driver, OpenCL(tm) Driver, AMD Integrated Driver and Catalyst Control Center, Is the Catalyst Software Suite needed? Or can I just use the website auto detect option to detect my driver? In another word, Is Catalyst Software Suite really needed? My have Win7 64 bit, does it matter where I install the new driver? Thanks a lot.
