I have??
I've asked what new it brought to the table that makes it a "must have" in many threads. If you cannot answer that then it's a waste of a couple k.
=================
What does the new MP bring to the table other than TB?
I've been trying to get affordable SSD performance like this new Mac Pro offers in my 2009 Mac Pro and it just cannot be done without a super expensive RAID card with terribly long boot times. You can either have bootable SSD that's throttled on a x2 card, or you can get a x8 card that's not bootable or you can buy a RAID controller for several hundred dollars to run RAID0. Plus to top it off, there's something throttling the top two x4 slots to 1GB/s which further compounds the problem.
Adding dual high-end GPUs is also so difficult in the current machine it's not worth considering... you need a supplemental power supply for crying out loud! Now there's elegant internal expansion for you. LOL.
Not to mention adding a USB 3 card that can use the native drivers in 10.8... wait... WTF? You mean I have to run a power cable from the optical bay to power this thing? Unbelievable. Yep... great upgrade options here!
The PCIe card support for the current Mac has not endeared me to internal expansion. I welcome TB with open arms.
I'm stunned there are so many people fighting for this. Are you guys upgrading the same Mac Pro I have been?! Upgrading this machine is borderline madness.
