The answer is highly game dependent. I play only UrbanTerror, which is a standalone game based on modified Q3 engine. An updated version of the UrT 4.1 engine includes the sound system that combines surround sound information using HRTF processing to be conveyed via normal stereo headphones. So in this game, you don't need any enhancements provided by sound card drivers. For some other games, the game provides only 5.1-channel sound to the sound drivers, expecting the sound system to process it into stereo surround sound if necessary. I think this is where CMSS-3D may come into play.
