there is no easy way out
Phew...This is making me feel my 5770 will be getting driver updates till 2014 end at least
http://support.amd.com/us/gpudownload/windows/legacy/Pages/legacy-radeonaiw-vista64.aspxAMD has moved to the AMD Radeon™ HD 4000, AMD Radeon HD 3000, and AMD Radeon HD 2000 Series new driver support model. These updates will focus on resolving application specific issues and critical updates. The reason for the shift in support policy is largely due to the fact that the AMD Radeon HD 4000, AMD Radeon HD 3000, and AMD Radeon HD 2000 Series have been optimized to their maximum potential from a performance and feature perspective.
