Oh, the 7700 is a much better fit, IMO, but if I can still get the deal the 7900 is only $500 more. To me, considering free shipping now, but maybe not later, I would rather get the 7900 now and then when I get another even better processor (I'll still need/(want) one more) I'll already have my preferred amp -- with free shipping. And I don't see amplifier technology being in transition like processors. Clean power with large capacitors is just that -- can't see why I would want a different flavour next year (though I'm all ears if there is a secret I don't know)?
