A decade was about how long I expect my i7-4770k based system to last, assuming I have absolutely no money to upgrade before then. > My main frontend in the living room has shown problems (hanging while > playing back recordings, and I mean a hard-lock... no ssh, no response > at all, and the backend had in its logs "where'd it go? closing > connection") and so I think the hardware may finally be at the end of > its life.

Power efficiency and speed generally increase in multiples greater than one, so you are reducing the cost and time of compilations or general use by a lot in the end. Look at Alan's quoted build times for an example. R0b0t1.
