Windows Experience Index

• Graphics subscore. This subscore indicates how well a computer will run Windows Aero and play videos. This measurement is based on video memory bandwidth (megabytes per second), so the higher the dedicated graphics memory in your video card, the better this score is likely to be. A 256-megabyte (MB) video card, for example, is almost certain to get a higher score than a 128-MB card.
  
  Any graphics card that doesn't support Microsoft? DirectX 9 automatically receives a score of 1.0, regardless of other factors. Also note that a video card using a driver that doesn't support Windows Vista Display Driver Model (WDDM) can't receive a score higher than 1.9. (DirectX 9 and WDDM are requirements for Windows Aero.)
  
  
• Gaming graphics subscore. This subscore is based upon the frames per second at which the video card can handle different textures. If the video card doesn't support Microsoft? Direct3D 9, it automatically receives a score of 1.0. A card that supports Direct3D 9, DirectX 9, and WDDM automatically receives a score of at least 2.0.

i got a 1GB nVidia geforce 620M on my laptop...so it means that my laptop is better in processing hardcore games than it is in playing videos???

In Microsoft's opinion, yes.
