Another possibility:
If I were to sell the unopened 12-core Mac Pro for enough to purchase a new 3.33GHz 6-core Mac Pro ... would this be a better solution all around?
I do use Aperture. Does it make use of 12 cores? of 6 cores?

Why would someone buy 3 year outdated technology when Apple themself has said an update is coming later this year? If you can not hold off, might as well buy the newest tech you can find (the one OP specified even has a close, if not higher, Geekbench score than the Mac Pro).
I think the MP will likely provide you with a solid platform for many years. Thunderbolt is needed only by people who don't have PCI slots on their computers. You can add SATA3 or USB3 easily should such technologies become a requirement in the future, and the new graphics card compatibility under Mountain Lion 10.8.3 offers you greater GPU potential than any current iMac.
And don't forget, you could always do the CPU swap Tutor suggested in the original thread about the Best Buy sale, giving you a 3.33 12 core monster that would be simply wonderful for anything.

13000 for iMac
17400 for Mac Pro. Yes. They are close. And 13,000 IS higher than 17,400. At least check instead of guess. /s. 12-cores vs. 4 even with clock difference is not a fair fight. But this does not mean the iMac won't eat that Mac Pro's lunch on MS Word and iTunes. It will.
I think the Mac Pros would haves sold out a LOT faster it would have been the 3.33 Hex vs the 2.4 12 core for $2499...even though the 12 core retails for $700 more. Tells you how messed up that product line is.
I do appologize.I was looking at 64 bit and the 8 core MP and the i7 iMac. My mistake.
