Personally, I think it's best to wait for Microsoft to release drivers customized to my Surface Pro 2. You'll find that others are comfortable with installing Intel's latest drivers. At the very least, create a System Restore file prior to updating should you discover the reasons it's better to wait ;-)
I like to install the latest from Intel as I like to get the most performance out of my surface. I play Starcraft 2 on my SP2. Have had no issues installing the latest drivers from Intel, even the beta ones.
