There are many factors
* Overclocking, as you  mentioned
* Speed of the 3D driver.
* Resource usage of background processen
* Overhead of Wine of course, but that should be minimal for OpenGL.
* and many more

The UseDGA has no influence on this, this affects only 2D acceleration of 
DirectDraw games.
