Among the currently available notebooks from ASUS, we took note of the G51J series and though it would be good to mention it here. You can see the it in action in the video above. Check the specs on the ASUS website (click here). Below, you can have a look at a review made by BToTech1 of this notebook:

Inno3D® is excited to announce the grand unveiling of the Inno3D GeForce GTX 480. The GTX 480 boasts an amazing 480 shader processors, a 384-bit interface to 1.5GB of onboard GDDR5 RAM, and clock speeds of 700MHz, 1,401MHz, and 1,848MHz for the core, shaders and memory, respectively . GTX480 was redesigned from the ground up to deliver the best performance on DX11 – adding dedicated engines in the GPU to accelerate key features like tessellation.

Game performance and image quality has received a tremendous boost, enabling film-like geometric realism for game characters and objects. Geometric realism is central to the GTX480 architectural enhancements for graphics. In addition, PhysX simulations are much faster, and developers can utilize GPU computing features in games most effectively.

The Inno3D GeForce GTX 480 specs:

The NVIDIA® CUDA™ technology unlocks the power of the hundreds of cores in your NVIDIA® GeForce® graphics processor (GPU) to accelerate some of the most performance hungry computing applications. The CUDA™ technology already adopted by thousands of programers to speed up those performance hungry computing applications. Such is the case of the video card in the image above.
