The NVIDIA website will have the most current driver version along with Beta driver versions, if you're adventurous.
MSI doesn't create the driver. It is created and maintained by NVIDIA and provided to MSI. If you're talking about the utilities, like MSI Afterburner or MSI Kombustor, on the CD/DVD then those are customized for MSI.
The CD/DVD, that comes with the card, will only have the driver version that was available when the CD contents were created.
