Sometimes the WEI score is a bit decieving as it rates from the lowest score. So you could have a super fast computer that excedes your expectations,
but no graphics card and it say your score is very low
So if you are seeing a specific issue with the graphics then it is good to look into. The easiest way to check is to get GPU-Z: GPU-Z Video card GPU Information Utility
and see if the spec's match up and see what the speed and temperatures are at.
Edit: also since it is a laptop, the power profile might affect it as well. some computers (like mine) throttle the CPU when in battery saver mode and Quiet Office. Make sure it is in High Performance or Best Performance and likewise, you can use CPU-Z to check to CPU speeds: http://www.cpuid.com/cpuz.php
