I had huge problems with crashes when editing video using GPU and lag when playing 3D games. Tried this vacuumer and got 15-20 degrees C lower temperature, could render 1080p video in Premiere CS5.5 for the first time and went from low quality in BFP4F to high and higher resolution with no problems. I spent days looking for a software or driver error but the problem obviosly was heat. Design failure by Sony, but otherwise great laptop.
