weard windows aero notification

[BustersTech]

when I go in to the themes in windows 7 to change my window color it says using aero will decrease performance on my gaming desktop with a graphics card score of 6.7 it works perfect very smooth I was just wondering why it says this because on my laptop that get a graphics score of 4.6 it does not say that. the only difference is that my laptop has intel and my desktop has amd

WinSAT acts differently from system to system, some will have the best hardware and they still get a low score, while a basic build may have a higher score. If aero works and your system runs fine, then don't worry about it too much.
The current OS Win8.1 don't even have WinSAT
