All the card manufacturers use the NVIDIA drivers as core of their product. Some add management utilities themselves. So their is a time gap between a new release NVIDIA driver and the update of the card manufacturer.
Creative is also at the 650 update level now, so it does not matter which driver you use.

A different story for beta drivers. Much further advanced, sometimes a game or a nasty bug really demands a newer version so the beta driver is unavoidable. But when there are no problems stay away from beta's!
