Have a Mac Pro 1,1 with 4 30" ACDs and have been waiting for 2 years to update...now I think I discovered what I really needed all along was a maxed iMac and 2 thunderbolts to go with it. It'll run cooler and be as fast or faster than a new Mac Pro for what I do. Got it ordered last night and will get it next week. Can't wait to compare the performance! Thanks to my buddy John for setting me straight.
