All it is, is a mobo that is capable of running two of Intel's quad cores. It's almost absolutely useless too. Most games are only designed for one core. In the near future, games will be designed for two. The most ideal amount of cores for a game is three. Eight takes too much time and money to code for and it will have processing power that it doesn't need. Something like this is really only for servers or extremely cpu-intensive tasks such as rendering 3D animations, compiling code, or encoding files, things which the general population does not need.
This is nothing, anyways. Intel already has an 80 core proof of concept that will release in 2010.
