Respect to the Archicad team for making the product support multi-core processors!!!!

Not that I'm a big Archicad fan, I personally found it a rather awkward application to drive, I'm sure that others with argue against this. :-) But the point I'm trying to highlight here is that the product can now support the lastest fastest multi-core processors on both the PC and MAC platform!! Common on Autodesk, we need the whole of Revit to use the "might" of our hardware not just the rendering engine.
