"Not pointless....... but very expensive, and not too many consumer apps running on Windows take advantage of MP."
True - then again, dual processor users by the very nature of SMP processing, are power-hungry pros. As for price, Xeons are indeed pricier, but not *that* much pricier, especially if you are content to settle for the second-fastest model (2,8 GHz), as opposed to the top-of-the-line one (3,06 GHz). Then there is of course the Opteron to consider as well.
As for the 970, it will be interesting to see if Apple goes Dual for the PM:s. Being able to stay single-processor, no longer lagging far behind Intel, the temptation to cut costs by sticking to a mostly SP line must be pretty strong. Oh well, hope they get em out for the WWDC...
