Both models you mentioned are very good laptops.
Our software is not yet capable of taking advantage of dual GeForce 8700M GT in ASUS model. Support for multi-GPU configurations in our software will probably only be implemented in several months from now. So currently, Toshiba laptop with 9600M GT is a faster choice. It should also have much better battery life because 9600M uses smaller 65nm process compared to dual-chip 80nm 8700M SLI. By the way, in the future dual GeForce 8700M is expected to have only slight speed advantage (approximately 50%) judging from 3D MARK scores:

All notebooks have thermal constraints. Because of this, no notebook can even remotely compare to desktop video cards in speed. For example, even a crazy expensive notebook with GeForce 280M video card is slower then desktop PC with sub-$100 GeForce 9800 GT video card. NVIDIA's notebook video card labeling is very misleading because their notebook video card model labels are completely unrelated to desktop model labels.
A more practical workflow is to use a notebook for video capture and preview and a desktop for video processing.
