I read on the videoguys website that the best memory-processor relationship to establish is best when the memory speed is 1/2 the speed of the processor, i.e. 800mHz FSB processor, 400mHz memory speed. I haven't found anything that supports that claim, so does anyone know how to answer this question? If it's true, does it make THAT much of a difference? I am buying a Dell PC for editing with Vegas, Sound Forge 8, and Acid Pro 5, also using magic bullet 2.0 and magic bullet HD plug in. It's the last thing I need to clarify before clicking that mouse. Thanks.
