    This makes a big difference to me and I could not find out from calling Apple.
    Is the 3.0 option on the new MP an E5472 or X5472?

    The X5472 does exist, wikipedia is incorrect in that it doesn't have all models there.

    It's quite likely that they are using the E5472 processor, but it may be a short time until someone is able to verify this as it is only available as an online option.

    L, E and X are intels TDP codes for Xeon processors.

    X = 120 W TDP ( ex X5365, X5460, X5482 )

    E = 80 W or less TDP ( ex E5320, E5450 )

    L = 50 W or less TDP ( ex L5148, L5405 )

    That intel publication was based on the pre-release steppings that exhibited higher thermal values.

    The 3.0 is known to be 80W TDP by virtue of cooling component commonality with the 2.8 and uprated cooling components in the 3.2 as detailed in the Service Source documentation.

    Is there a huge difference between the 3.0 and 3.2 when using apps like After Effects, Photoshop and CS3 in general? No plans for 3D apps but not sure if its overkill for me to spend another $800?

    Speed difference between 3.0 and 3.2 is ~7% not noticeable, except in the most processor intensive applications.

    Do we have confimation on the 3.0 MP chip from someone who has received theirs already?

    Once again, look at the facts...

    1. 2.8 and 3.0 share a motherboard unique from the 3.2

    2. E5472 (3.0 ) is 80 Watts TDP same as E5462 ( 2.8 )

    3. X5472 (3.0 ) is 120 Watts TDP same as X5482 ( 3.2 )

    4. 120 Watt X5482 ( 3.2 ) REQUIRES uprated cooling vs. 2.8/3.0

    5. Apple tends to get the "pick of the litter" from intel in terms of faster and lower power.

    6. Seeing X5472 on the retail market looks like Apple passed on them else they woud be more scarce like X5482.

    7. Apple seems committed to being more green/energy efficient so E5472 would fit better to such leanings.

    There are two 1600MHz FSB 3GHz Xeons.

    Totally agree with all your points and general logic, but would still like to get beyond educated conjecture. As someone pointed out, I don't think anyone has received a 3.0 yet because most of them likely ordered the GT as well.

    I would like to have this confirmed as well... I am on the fence between the 2.8 and 3.0 and this will help me make my decision.

    I ordered 3, assuming it will be the 80W one. Everything I have seen indicates it, but I guess one can't be sure..

    The problem is, everyone who ordered 3 seems to have also ordered the 8800GT to go with it, which means no one really knows for sure.

    Not to be rude but...

    What is wrong with everyone? A little research on Intel's web site will give you the an product lineup answers, http://www.intel.com/products/processor/xeon5000/specifications.htm?iid=products_xeon5000+tab_specs.
    Why would you go to Wikipedia for questionable fact when you can go straight to the manufacters website??

    The answer still isn't confirmed. The 1600 bus can run on either an 80 or a 120, even with this new site.

    Yep. Not one person on Mac Rumors has ordered AND received a new 3.0 MP, and like Schrödinger's cat, the CPU is neither the 80 version, nor the 120 version until someone opens the box and checks.

    I guess we'll know as soon as the 8800's come out... I think I've finally made up my mind on getting the 2.8 instead (at least I think i have).

    Hmmm...( biting tongue ) of seven scores on Geekbench 2 for Mac Pro 3,1 @ 3GHz all show Xeon X5472 ( 120 Watt TDP variant, VERY VERY SURPRISING !!!! Apocryful in my opinion )

    Not quite willing to say Schrödinger's cat is out of the box just yet.

    Yep, Mine shows X5472 in Geekbench as well. Though, I am still not 100% on what the difference is anyways.

    E5472 = 80 Watts TDP ( runs cooler, newer stepping )

    X5472 = 120 Watts TDP ( runs hotter, older stepping )

    Well I ordered mine last night (the 2.8, 8 core)... this comes with the 80 watt, right?
