I was about to buy the new Haswell iMac, and then remembered that we still don't know exactly what the Pro has in store and how much it's going to cost. Here's what I'd be getting if I went with the iMac: 27" 3.5GHz i7 32GB ram (from OWC) 3TB Fusion Drive GTX 780M 4GB 4TB Mercury Elite Pro external hard drive for Time Machine Mercury Pro 15X Blu-Ray burner This will cost me around $3,800. What type of Mac Pro setup do you suppose $3,800 would be able to buy? I have a feeling that if I get the iMac now, it's going to turn out that a $3,800 Mac Pro setup would actually be more powerful and longer lasting. Keep in mind I'll still need the external hard drive and Blu-Ray drive with the Mac Pro, and perhaps even a second external hard drive. And the display.. unless I kept my 30" ACD.
