Advice on iMac for Autocad 21.5"

[visualarchitekt]

After so many years waiting for Autocad to be release for Mac. Finally my dreams came true. So I'm ready to switch to mac.(tired and sick of PC's) I was playing around with autocad @apple stores lately and in both the 21.5" and 27" IMac seems to run smoothly. I have a space limitation so the 21.5" is the one for me. But I'm debating about going for the 3.2GHz Intel Core i3 or the 3.60GHz Intel Core i5.
is the i5 dual core worth the extra $200? Also planning to add more RAM after (maybe add another 8GB= Total of 12GB)
Or just wait for the refreshed iMacs? rumors saying refreshed ones are around the corner. I can wait another month probably.
I'm new to Mac so any advice is really appreciated.
thanks

at this point, you're probably looking at 4 weeks until the refresh of iMacs, so I'd definitely wait.
