3d performance issues compared to identical system

[kkthebeast]

Hey guys I was wondering why People with the exact same Laptop / Processor / Ram / Hard drive / and Video card would be getting 3D scores all 1000 higher then mine? Running the newest drivers (installed after clean wipe from safe mode ). Win 7 x64 Pro

Alienware M18X R2 (OC 4.2ghz stable)
7970M Crossfire (OC +50mhz gpu +100mhz gpu memory)
underclocking lowers the scores on both.

2756 (my 3d graphics mark)

All but one are getting 3900-4100 3d graphics mark scores.

Thanks for any "how fix it" tips or suggestions you may have, It's all welcome even if you think it's dumb.
(And yes I will upgrade someday to a newer laptop / desktop) :P
