    I'm buying a Mac pro and logic 8 soon and I had some questions:

    1) I only need 4 cores at this moment, so should I get a refurbished (2x Dual core) mac pro so for a later upgrade I have the two heatsinks to upgrade one or both CPUs?
    2) Would any xeox 771 cpu work on the mac pros, could I pair a 65nm and a 45nm?
    3) The difference between the ram speed of the current and older generation of mac pros (DDR2-800 vs DDR2-667) makes any "real" difference in the overall speed?
    4) Does the mac pro have any technology of reducing Hard drive noise/vibration? (ie rubber suspension) I'll be using all 4 HDs and low noise is very important.

    I would really appreciate any useful answers, google didn't have any straight answer to my questions.

    I can answer questions 1 & 2. The 2x Dual core (the one I have) is a Xeon Woodcrest. The only drop-in upgrades I am aware of, would be to drop in the 3.0 GHz processor (5160) of the Woodcrest. That answers question two as well.
    So I guess the question is, do you want to spend money on a new single quad processor (that could be upgraded later), or get an old double duo processor that maxs out at 3.0GHz?

    The new MPs use a lower power higher performance (clock for clock) CPU, so if it's apples to apples (to abuse a saying) I'd opt for the newer MP. Also, unless the $450 difference for the base 8-core will break the bank, I'd keep it, and sell your current MP intact.


    Generally speaking, CPUs must be matched pairs.

    It does make a measurable difference, but I can't say whether or not it makes a "real" difference in your use cases. Even with the new MP, the amount and configuration of RAM, all of the same speed, impacts overall performance in a measurable way.


    Mine hasn't arrived yet, however rubber washers are readily available, and extended length hard drive screws are available if Apple hasn't got this covered already.

    Edit: Based on the images here, the drive trays don't appear to utilize any rubber grommets.
