One test it would be very interesting to do is to create a task list that simulates an average person using the pc daily. Use some office programs, image editing, video conversion and play a bunch of games. Pick a few persons and let them do those tasks first with an intel cpu and then with an AMD one, don't telling them which one is which. Then ask them which system they would pick. That would be a REAL world test. Also you must consider system build price in the equation.
