I've been driving my show with a junky old Windows XP desktop and Lightorama for a few years. Works great. This year I'm planning on Vixen with a few different controllers and about 2,500 pixels. So I think it is time for a new Windows machine. I haven't bought a Windows machine for 10 years so am lost. Would a laptop have enough horsepower and good enough network card to drive a complex show? Any advice any one has about CPU, memory, network card for driving a show?
