Hi Chen, I cannot explain that difference between those two video cards. Perhaps the GT440 model has really worse performance than the HD6600 one...
For the animation perf, I'm not sure but I think Clutter animations are computed by the CPU and not the GPU. That would explain you don't have any problem at that side. Damien.
