    What are the different cores and just what do they do thats different?
    i.e the 64-X2-4200 has a Manchester , a Brisbane, and a Windsor cores..
    Also what are the different steppings and just what do they mean?
    Are these power useage issues, or Heat issues? Are there differences in
    utility and accesories.. Also what is the big pitch about boxed or
    unboxed etc. All AM2 sockets of course. Is there some differences in
    types of memory used? i.e. DDR2 DDR3 and freqs up to 1000 cps?
    Cache differences and why do some retailers lest the core name and
    others do not?

    ** Also what is the big advantage of Serial ATA harddrives over
    Eide, ATA, or Scuzzie?

    The difference between the cores is twofold. Firstly, one may be
    manufactured using a smaller process, i.e 65nm over 90nm. This produces
    a chip with lower power requirements that also runs cooler. Secondly,
    remembering that a CPU is nothing more than many logic circuits each
    designed to form a particular instruction, the logic for a newer core
    may have been improved meaning it can perform the same instruction
    faster than its predecessor.

    Typically it is the CPU packaging that decides utility and accessories.

    The steppings are nothing more than a production batch number. There
    *may* be some minor modifications.

    The difference between boxed and unboxed means basically either OEM or
    Retail. OEM is for system builders. As such, you get the bare
    essentials which is CPU only. Retail is for Joe Public so you get
    everything you need and a nice manual to show you how to do it. Also
    you'll typically find that the warranty period on OEM is a year whereas
    you get 3 or more on a retail CPU.
    Quite simply, speed. Also the data cable is many times smaller and is
    easier to route in small cases.

    But isn't SCSI still the fastest interface, (although not the cheapest)?

    4-Gigabit Fibre Channel (FC) is the fastest interface currently in use.

    10,000 RPM WD Raptor hard drives on an LSI or 3Ware controller can be fairly
    cost effective.
