Hi, would be grateful for any advice on choosing a new iMac (27") to run 3D design/ modeling software - ArchiCAD. I'm currently working off a 5 year old 17" iMac Core2Duo, so anything new is probably going to run like a dream in comparison. I plan to get one of the new iMac 27" as I want large screen size. I will add extra RAM (16GB)

Specifically can anyone tell me if which of the following upgrade options will make any real noticeable difference to ArchiCAD performance.

Processor - 2.9GHz quad-core Intel Core i5, or 3.2Ghz i5? or 3.4 GHz Core i7?
Memory card - NVIDIA GeForce GTX 660M (512MB) or GeForce GTX 675MX with 1GB? or GeForce GTX 680MX 2GB?
Hard Drive - upgrade to Fusion Drive?

Thanks for any advice.
