fyi, I just picked up a 2.8ghz Octo for $1899 after setting up a no tax business account. That's $900 off retail of $2799. You can get a 3.2ghz Octo for $1100 off...so $3599. You have to go into the apple stores and see what they have in stock or get them to see what other stores have in stock. thanks to all the guys on this forum for all the discussion and tests. I was waiting for the new Mac Pros to hit to decide, but I can't beat that price and the upgrade from my Dual 2.3ghz G5 is plenty for me for now.
