Hey Alrik,
The way we are doing this is part of a research program, so one day there'll be publications about it and when they are there, I'll make sure we post a link here so you can find out for yourself. But the short of it, system specs have nothing to do with it.
Regarding the 80 hours - I didn't say that though it could, we really don't know as long as we haven't finished with the balancing. A general rule of thumb is to double or even triple the time in a walkthrough in god mode, and since we this in the mornings, that'd indicate somewhere around between 40 to 75 hours.
Cheers
Lar
