Default Need root on a Storex Tab

Hello

Im looking to root this tablet device eZee'Tab785D11-M by Storex,
The main reason is to use the apps mentioned here http://forum.xda-developers.com/show....php?t=2329080 , to see if I can get really a better gaming performance and also to disable the buggy touch screen buttons.
Has anyone successfully managed to root this tablet?
