I had a base 27" with fusion on order. Then changed to the 3.2 with fusion. In the meantime I kept checking with the local apple stores and finally, yesterday, I got my hands on a 3.4GHz i7 with fusion with the 680MX. I didn't really need that much but it was worth the extra $350 to not have to wait another month and on top of that, I got a better machine. So far it's great! I've had lots of macs but never an iMac. Loving the gorgeous 27" screen and VERY glad I didn't go for the 21" that I originally wanted. The extra real estate is awesome considering I have LOTS of open apps/windows at any given point. The Bettersnap tool is AWESOME to help manage that. I do get a beach ball every now and then which surprises me, but overall it's great. I just say check in every few days with your local store if you are purchasing the top of the line. Mine had a couple when I went. They don't get many but they are starting to get more and you never know when you might find one!!
