The new iMac looks great. 27"!!! Choice of i5 or i7 quad-core. Is it worth the $200 extra for the i7? Will AC see a significant speed increase? Also, going from 4 to 8 gigs of ram is an extra $200. Until 64 bit comes out for AC, will that affect performance (with just AC running)?
Thanks
See these comparison charts:
AMD Ryzen9 5900X CPU, 64 GB RAM 3600 MHz, Nvidia GTX 1060 6GB, 500 GB NVMe SSD
2x28" (2560x1440), Windows 10 PRO ENG, Ac20-Ac28

My previous machines were a PowerMac G5 (2x2GHz) tower and an original MacBookPro 15" 2.16 GHZ Core Duo (32 bit 2GB RAM max).
ArchiCAD performance is still limited. There is good rendering performance for Sketch rendering (400% CPU) but Lightworks seems limited to 100%. 3d generation is also still not great (about a 50% improvement from my laptop- commensurate with the GHz change) but sections and trace reference seem snapier. I'm finishing up a project in CDs so there's not a lot of visualization work, but the ATI card seems very smooth on OpenGL 3D flythroughs.
Hopefully after this project is complete I can try out AC in windows under Parallels or BootCamp to see if thats a better experience.

(Video processing-Visual Hub/Handbrake shows CPU use at 700% - surprising for a quad core machine)
My dual quad-coreMacPro 2009 has 16 virtual cores. Seems to me Archicad 13 makes good use of them in many situations, sketch rendering, section generation, drawing updates etc. But not Lightworks. Get Artlantis instead!

On the multi-CPU Cinebench test the i7 rendered the scene in 0:58 vs 0:45 for a 2.26Ghz 8-Core Mac Pro! The i7 beats the 4-Core Mac Pro.
I think it is a no-brainer to go with an i7 if you are considering an iMac - they are half the price of a 4-Core Mac Pro, faster and come with a bigger screen. The Core2Duos really don't make sense anymore unless you
Definitely on my shopping list

So my question is: would it be worth taking the 27" i7 all the way and loading it up with 16GB of RAM? When I say worth it, would it reduce rendering times in Lightworks and 3ds/Vray, and would it improve the overall speed of ArchiCAD?
Im thinking yes, but I would like someone with a little more hardware experience to let me know either way.
Chers,
Mike

I have 16GB in my MacPro and do often push the limits but that is only when I am running multiple OS's, several ArchiCADs, Photoshop, InDesign, Revit, NavisWorks, Acrobat and the usual other stuff (Mail, Safari, etc.)
My MacBook Pro runs just fine with 4GB. I will probably max it out to 8GB soon, mostly so I can run a Windows VM without tedious memory swapping.
