I recently bought a ASUS Radeon HD 4850 512MB DDR3 256-bit PCI-E 2.0 CrossFireX Supported Video Card - EAH4850/HTDI/512M and I cant seem to find the update drivers for it. I looked on the ati site and where it directs you but it seems ati doesnt have it listed or something. If anyone can direct me to an update driver for the 4850 I would greatly appreciate it. Also I was playing a game and the screen studders almost sometimes and then I get this droning sound almost and i have to reboot. Anyone have a similar problem?
