From my own personal experience I can tell you only one - WEI is useless. When I bought my laptop, it said that my gaming graphic's score was 6.7, then, after updating the drivers, it decreased to 6.6, last week I did a clean install of windows with the same drivers as before and it's reading 6.7 again. Funny, the score fluctuates without any changes in hardware. That Aero score is also somewhat weird, i used to own A Dell laptop with an i7-2630qm processor, with an aero score of 5.5, then I switched to an ASUS laptop with an i7-2670qm, which achieved a score of only 4.8. Both had that smart "optimus" technology and both used the intel HD3000 integrated graphics in the test, so how could the scores be so different?
