Hey all, got myself a top of the line 2010 iMac which i am very pleased with so far! I just installed Windows 7 and have got as far as installing the graphics card drivers from ati's website (since the ones that windows update installs are almost always out of date). Now the card is being recognised as a Radeon HD 5750 but I know from other discussions best guess is It's actually a Mobility card inside the iMac. So which driver do i download for my graphics card? Thanks.
