AMD 2000/3000/4000 card owners are currently as of 6-22-12 being routed on the support page to the following url from the driver pulldowns:

At this time this page is displaying an option to download the 12.6 Beta. This is incorrect for 2000/3000/4000 users; 12.6 Beta *does not* support those cards. This needs to be fixed on the AMD website but we don't know how long it will be before they make the correction.
