Why are they benching AMD cards on an Intel chip (and presumably, an Intel chipset)?

First of all, "presumably an Intel chipset", is not an okay thing to say. Intel procs go in Intel chipsets. Period.

Second, it's because AMD doesn't have anything that has no chance of bottlenecking these behemoths like the 3960x does.

so three cards to double the output of 1 card.  I wasn't a great math student but this just seems off?

You obviously aren't a great compsci student either.

There are two obstacles that would have to be overcome to achieve linear scaling with the addition of cards to from xfire setups.

1. You'll have to clock all of the cards at the same speed or higher than the single card setup. Because 3x1,000mhz does not equal 3x1,500mhz.

2. You'd have to have excellent drivers and a benchmark that fully supports the additional cards. Because if it under-utilizes the second and third cards like it normally does, you won't have the power of three cards.

Even after these conditions are met there are other things that may keep you from linear scaling like an issue with any of the cards, improper scheduling, bottle-necking, not getting enough power, overheating, etc.
