Drool :). Of course it makes my little Quad Core 2.6Ghz Mac Pro look positively pedestrian.
I am happy that we will have some 8-series boards to put in my computer now though!
I feel your pain, my 2.66GHz Mac Pro is getting processor envy too.
The bright side is that it may be possible for us to get one of those nVidea GeForce 8800 GT cards in the future.
