[comp.sys.mac.hardware] IIci speed question

     I have gotten several very useful responses to my broad query on 
purchasing a new Macintosh IIcx/ci system, but still have a few
questions to which I would greatly appreciate answers.

1) Does anyone have numbers on the following:
    -IIci speed: the MIT price list says that the IIci is "45% faster
        than a IIcx".  It doesn't say how this is derived, and
        this isn't as fast as I expected.  Does anyone know where I 
        could find a table comparing the two machines running the
        various "standard" tests (fibonacci, etc)
    _IIci video: Several people have told me that the IIci is
        qualitatively slowed down by the use of the built in video
        card.  Does anyone have a more quantitative result to back
        this - in particular, how much is speed degraded by using
        internal video to drive the Apple 13" monitor in 1/8 bit
        modes?

2) Compatibility.  Is there any problem in this area?  I assume that
    all new software will run on the IIci/cx?  How about older stuff -
    what percentage of software written for the plus will run?  This
    isn't an overriding issue, but I am sort of curious about how much
    of my older software (games, etc) I will have to junk...
