sizcoz , I guess that in your case the GT 745 is making the difference from Monumental's results. Dedicated graphic cards seem to add a lot to the performance.
saiyadjin , the debugger isn't that accurate, especially if you're displaying a lot of staff it can cause a lot of performance loss. I think it's better to use a text object (or even better a sprite font) to display the fps, cpu etc in normal preview.
