3d performance issues compared to identical system

[yuukiisun]

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. Win 7 x64 Pro

Alienware M18X R2
7970M Crossfire
underclocking lowers the scores on both.

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.

Also maybe most of those other people are running Win10, which has DirectX12 built into it.
