After I read this, I had to try it for myself http://blogs.msdn.com/b/ie/archive/20...

MacBook Pro Specs Intel Core 2 Duo 2.8 GHz 4GB Ram NVIDIAGeForce 9600M GT 512MB (not used by chrome since it's all at the application level, no hardware acceleration)

AlienWare Specs Intel Core 2 2.16Gz 2 GB Ram GeForce Go 7600 256Mb

Microsoft is getting it's DirectX Big Guns and trying to give us a glimpse of what the web will be once every other browser will be doing hardware accelerated graphics. Google better make a move quickly to not loose momentum with chrome.
