I just noticed the drivers found on station-drivers seem to be much newer than those available by doing a standard search on the manufacturer's site and even on Intel's. Usually I like to install the latest drivers available but this is a new system I am unfamiliar with. Would these be the best to use? Some of them have pretty big version number jumps over the officials.
