Shawn,
Your WinSAT report above actually indicates Graphics score of 4.4, which is ok for Air. I'd appreciate if you find an XML with 2.0 Graphics score in C:\Windows\Performance\WinSAT\DataStore\ folder, it should explain itself. It is possible that DWM assessment that is triggered during Parallels Tools upgrade ran concurently with some other intensive process and measured low graphics memory bandwidth.
