Good reading.
Seems adding a third GPU does give good scaling, but adding a 4th doesn't get you much extra (except for in CoD4).
4th GPU might get better with newer drivers tho.
Still from those benchies the best setup atm seems to be one X2 and one XT
And with the recently announced price drops on the 3870XT's... I might be severely tempted...
