So after trying to install the proprietary drivers for my HD 4870 cards and twice breaking my system I learned the hard way that AMD no longer supports the HD 4870 in Linux. Does anyone know where I can get a legacy driver that will work the the 4870? I tried using the Additional Drivers app but that ended up breaking my system. Reverted back to open source drivers. If I cant find a legacy driver will Team Fortress 2 still work with the open source drivers?
OS: Ubuntu 12.04 64 bit
Graphics: HD 4870 1GB (Crossfire)
Processor: AMD Phenom X4 2.6 GHZ
