Is there any huge difference between the Dark Rock 3 and the Dark Rock Pro 3?

The pro has significantly more surface area, and includes two fans.

As far as performance goes however you'll probably not notice any difference unless you do one or both of two things:

-Run the fans at low constantly *the pro will perform better due to it's larger surface area and two fans*

-Have an overclock on your processor with the voltage raised relatively high.

The pro has something like 1.5x the surface area at least, so it will allow for greater cooling along with the added extra of two fans. This means you can have lower temps and quieter fans. @mvitkun is correct in his statement, so unless you plan to overclock or have low a RPM, there won't be much to tell between them.
