Depends which CPU, but here's an example where you save $1000 if you want a 12-core. Apple charges an additional $3500 for it, and here it's only $2500. Sell your original quad core for a couple hundred and save $1200, or keep it for 'just in case' situations.

Actually you want to keep the original processor for as long the the system is under warranty/AppleCare so if Apple decides to replace your system you don't lose the new CPU. Also, if Apple doesn't consider the CPU user replaceable then you would need to pop the original CPU in for warranty repair.

Has someone created a chart outlining all the CPUs that will work in the nMP? I don't think it is enough that the CPU fits in the LGA2011 slot, is it?

I hope OWC knows that they may void their warranty by modifying their new Mac Pro.
They might have done that already with their teardown.

Thanks...
Just in case you didn't understand the confusing their/they're/there fiasco: No, you cannot use the new processors in the old Mac Pro, they use LGA 1366 Sockets and the new one uses LGA 2011.

What's wrong with externally connected (via Thunderbolt) videocards, for instance in a box like this; http://www.magma.com/expressbox-3t

Of course when the Thunderbolt2 case becomes available...
First off it's not supported in OS X at all. Second it's pretty low bandwidth.

It may work as an ad-hoc booster for OpenCL tasks (eventually), but as a main card for gaming or maybe even a 4k Monitor, 2GBps simply isn't enough bandwidth to have any advantage over the 7970 in the nMP.

----------

And I'll put whatever the top gpu in the nMP 7,1 is in. :) assuming the d700 feels old at that point. Not sure much else can be done.
Maybe. That is assuming that 1) it doesn't have added power requirements. 2) they don't change the incredibly proprietary connector (which probably has XFire linkages, therefore may not work with an NVidia option). 3) Apple doesn't, at least in some small way, alter the form-factor making the cards incompatible.

Aww the perils of Proprietary hardware.

What would be necessary to run a gaming video-card in an external enclosure, in terms of bandwidth?

I have seen MPs with external video-cards in PCIe enclosures, running quite fast, and I thought the bandwidth of PCIe was captured by the TB2...

The faster the card, the more you'll notice. Oddly enough, the 7970 (D700/280x) has almost no difference running at PCIe 2.0 4x (2GBps/Tbolt2) as 16xPCIe3.0. However, the GTX680 starts to have problems, with drops in FPS up to 20%. Presumably the GTX780, Titan, 780Ti, R9 290X, 7990, GTX690, and any SLI config will have horrible issues (horrible considering how much you pay for lower performance).
