For those like me who have just the m9400 built into their Macs, there is a great way to boost the performance of the graphic card under Windows.
Upon installing the most recent drivers off Nvidia's site, go to the NVIDIA Control Panel and choose "GPU Clock speed", increase the speed to 450 MHz (which is the factory setting throttled down by Apple).
Enjoy 10% boost in all the 3D titles.
It worked wonders and never did I hear or experience any fan or overheating problems since 450 MHz is the factory setting the m9400 was delivered with.
