Ok I know I am opening the flood gates here but here goes. I am going to be in the market for a new machine here at the end of the summer am am very interested in a Mac. I am starting my shopping now and with prices being a factor I am trying to find a useful, and hopefully simple way to compare what comes in a Mac to what comes in a PC box in a given price range. I am really looking for a machine in the Power Mac family, sorry in advance if I incorrectly used the model name. I expect Macs to be a little more expensive but with all I have been reading lately about " the MHz myth", Front Side Bus, dual cores, and so on I am having trouble trying to compare performance. Thanks in advance
