Hi. Im going to be getting GPO soon as well as Sibelius 4 and maybe Cubase SE to start out with. Im going to be getting a computer dedicated to just music and I was wondering what would be a better choice, an AMD 64 3500 or a P4 3.0ghz. I was wondering if GPO has trouble runnin on an AMD system like I have read about regarding gigastudio. Thanks for any input.
