We really shouldn't call these Catalyst 4.8, it's just a newer build released after the 4.7 release from ATI, station-drivers.com leaked them onto the web. I think they came from Asus initally as we spotted a new version there.  There is no word on performance just yet, however rumors promise nice performance bumps. If you like to learn more about these drivers then please visit our ATi drivers forum section. 

We repackaged the driverset and brough the file-size down towards 18 MB. This is the full release including drives, control panel and WDM capture drivers

If you decide to install this set then remember, this is a BETA version; you use it at your own risk. Don't go complaining to ATI if it does not suit your needs and wishes. Supported Cards:
