Graphics performance score--so what?

When I upgraded from Windows 7 RC to the release version, my gaming graphics perforamance score went down from 4.9 to 3.6.

The graphics score stayed at 4.4.

Despire the low graphics score, I have experienced no problems whatsoever with Photoshop, Illustrator or Aero. So what good is the score?

Graphics card is built into Intel motherboard.

It's just a generalized program to help people understand where they might want to conceder an upgrade and is to be taken with a grain of salt IMO.
