Yep, AnandTech has been saying for several months now that the Achilles-heal for Nvidia has been their production ramp. They really blew it over the holiday season, when the AMD[ATI] 3850 / 3870 came out at a great price *and* with all the distribution channels filled. Here at MacRumors people have been saying that support for the 3850 / 3870 on the new Mac Pro is coming, which will give us all more choices. I will probably order the 8800 GT in a month or so when the dust settles, or maybe the various benchmark results will lead me in a new direction.
Another thing that may be interesting is the OS X update. If it has hooks for additional video cards, who knows what else may be in there. Could MWSF see an announcement of a built-in Windows (native) compatibility layer? That would be *big* news, wouldn't it?

Apple confurmed, in an email, that the 5 week delay in shipping the new Mac Pro BTO with the 8800GT video card is due to the card not being availiable.
