Use the latest 7 drivers for any GPU.
Install driver with device manager, install AMD settings and whatever requirements it has manually.
the problem is the driver detects as usable and the installer runs like normal but nothing happens with it the audio and error report manager install but the driver stays as default vga windows driver. and it does this with several of the windows 7 and 8.1 drivers i tested on it (i even tried the one vista driver and that still did nothing)
