Besides hooking up the card and the xfire bridge. Software wise do I need to do anything? I'm currently running the latest preview drivers. Do I need to uninstall/reinstall those? Do i need to use CCC to enable Xfire ? Do I need to do something specific for each game to turn on Xfire? I'm also replacing my PSU with a Corsair HX650 So I have to wait for both of those to come in then I'll be set but wanted to get an idea before hand..
