Yes a dual CPU motherboard can do games, however, their performance is no better than a single processor (indeed it should be worse) because most games are single threaded applications, and even the multiple threaded games are not optimized for dual processor set-ups.
Dual processor motherboards are almost exclusively designed for servers. They are optimized for server functions (ie. answering network requests) and provide no advantage to gaming.
Okay thanks for the response, so buying a Skull Trail chipset would be a waste of money also?
