Currently im using Dell Inspiron N5010 with Ati HD Mobility 5650 . And i am very happy with performance in games!  :)  (even though this not a gamer PC ) :).  In this moment im with 8.742 Driver package(from October 2010 i think).   Every month ATi are making new drivers , now they are 10.12 , but we Dell Notebook users can`t use them :( . The performance in some games will be better and overall behavior will be better . I have read somewhere that in 10.12 Catalyst -  Memory clock and Core clock are low when the video card is not in use ( not in game or application that require it) . So are you people from Dell planning to make some new driver package ? ;)
