Best answer to this probably is a compare, if the Official v10.6->"v10.8" has worked with your hardware just fine then use the v3.70 (first driver on page). As then the Crossfire on your card works clean off exactly as 1 single card (which HD5970 still is even while there's 2 GPUs inside the box). If not then go for the Eyefinity Build v3.71 those will CFX scale on so called 'TRUE' MultiGPU environment. Yes, CCC is multi language on all packages currently. Modifications are choose-able by you to either use or not and those will not affect the language. You still can install CCC in your own language (CCC in itself is not modded only the registry it uses is for include more options for CCC and basic good setup. It is only updated through builds to be newest possible to have the new optimization ATI hides under CCC coding).
