    If I go down to the Apple Store and buy a stock Mac Pro Octo, would I want to leave the 2600 in there or put in the x1900XT from my 2006 Mac Pro? I'll be ordering the 8800GT but want the best performance until then.

    I doubt they are compatible. The new MP uses a higher speed PCI Express bus.

    Which is supposed to be a faster card? The HD2600 or the X1900XT?

    PCIe 2.0 is backwards compatible with PCIe 1.1.

    The X1900XT is much faster. The HD 2600 doesn't use PCIe-2.0, so you might as well use your X1900XT.

    Is the new 2.8 machine going to be a substantial upgrade from my 1st gen 2.66 Mac Pro? This was the very first "stock" Mac Pro from 2006.

    Only if your software is able to utilise 8 cores efficiently, but short answer: yes!
