Anyone had any success installing these on the 2011 iMac with the AMD Radeon HD 6750M GPU (I'm running Windows 7 64bit). http://support.amd.com/us/gpudownload/windows/Pages/radeonmob_win7-64.aspx I tried updating last night....I'm used to doing this and very thorough i.e. fully uninstall AMD software and drivers first, then do a final clean-up using Driver Sweeper prior to installing new drivers. However, using the above link when I re-install it just installs Catayst Controller 11.10 with driver version 8.902 which is what I previously had installed? As a double check I downloaded the little App to check wether I've got the latest drivers installed and it seems to think I have.
