The concept is rather simple. You take two MXM graphic modules, plug them in one of those Desktop replacement machines and you can run SLI on your notebook. Nvidia will probably make the chipset that can accommodate SLI in notebooks and we have some reason to think this board is already finished. It is Nforce 4 SLI for notebooks.
If you at the desktop replacement type, then this is something you will likely be waiting for. I can’t wait to see how manufacturers will handle cooling two cards, because it won’t be easy. Source: TheInquirer.
