Hi, Having got Windows 7 up and running on my new iMac, I've met an irritating problem - I cannot install the latest driver for the 6770m GPU and am forced to use the Bootcamp one from January, which of course is hopelessly out of date. This seems odd, because up until...yesterday I've been using a late 2010 iMac. That hd a rebadged mobility GPU, so it was just a case of looking up the proper name (not thie 5670 it's advertised as) and installing the latest Windows driver. However, I can't do that here - I select the 6***m series on AMD's website (this one is going by its real name to the best of my knowledge), download the driver but on install I'm quicky met with a message along the lines of "Your computer contains no graphics adaptor". This is particularly annoying, because although it runs software far better than my previous system, there are quirks and the odd inferiority where it should be a complete walkover - things that were fixed by being able to have the latest driver. Any help or suggestions of a work around would be greatly appreciated. Thanks!
