I'd be interested in getting my drivers updated too... ASUS has been NOTORIOUSLY bad for being behind for drivers (one graphics card: 5 year old drivers on a 2.5 year old product... OUCH! Had to go to NVIDIA for the drivers myself)
Currently, I'm configured with the AH3650 card, and have been told by tech support to update my drivers off the asus web-page. Drivers on this site are OLDER than the ones provided on the CD for installation.. and those ones are fairly old as well. The direct from ATI drivers weren't playing nice with me, either.
