A while back I ordered an HP Pavillion desktop and dxdiag reports m9250f but the box it came in says a6648f. I think my model is the a6648f because images of the m9250f look different and the a6648f looks more like mine and if I'm not mistaken, the m9250f comes with a 2.66GHz Q6700 and mine is a 2.4GHz Q6600. Why would dxdiag report wrong?
