While I am glad see some glimmer of hope here, one thing to keep inmind, that about the same time as this is suppossed to be due, the new 9800/8900 (number/names seems to depend on who you ask) series of cards are set to be launched. Which will put the MacPro right back where it was when it was originally launched with the 1900 as a "supperior card" A new machine shipping with what will be hardware that is close to the end of its "life" cycle.
Screw it, I think this MacPro that I currently have, will miss out on the update to a 8800, and will be left as it is (other than more ram and HDD) and used mainly as a audio work station, web/mail box. And I'll build myself a *shudders* PC for my gaming concerns, I just have to think given Apples history, and the history of game software companies lack luster performance on porting over to the Mac, that gaming on a Mac is something that is unfortunately a long ways away.
I know one thing, I'll definetly have to think twice before going with Apple when I build another work station though.
