We use the 27" iMacs quad cores with 4gb Nvidia graphics cards and they perform very well in comparison to the Mac Pro. Trouble is there are so many bugs in the current AE on a mac I could not guarantee any kind of performance for you. You should read through all the comments on here and just be aware of what to expect. Unfortunately you have to work around a lot of these performance issues until they are fixed.
Don't bother using cuda... Waste of time...
Hm, okay. Do they appear only in CC or in CS6 as well? I only have CS6.
And, okay. Is CUDA really unnecessary? I though this would drastically improve performance.

After Effects uses CUDA for only one feature (GPU acceleration of ray-traced 3D renderer), and that feature is considered obsolete and is being phased out.
See this page for information about hardware for After Effects: http://adobe.ly/pRYOuk
You got your answer on Cuda then... To be fair seeing as Apple have switched to ATI makes things easier in the long run.
Once you have your iMac let me know and I can send all our preferences to make sure the machine is set up optimally. We have also got workarounds for most bugs... Not all. I would recommend SSD main drive and 32gb ram.
In answer to CS6 or CC, I don't recall as many issues with CS6 but as your mac will be new it will have Yosemite. We never ran CS6 on Yosemite obviously so can't say, I would highly doubt it would work smoothly!
I know none of this is what you want to hear but it's best you know what to expect before shelling out the cash. Read all the new Mac Pro owners comments, and think how much money they have wasted! If you want to use a Mac the iMac is a good option for now. Just be prepared for a very frustrating user experience in AE!
Check comparability with Adobe on CS6 and Yosemite, although their bar of what they consider 'ready to use' in Yosemite was pretty low! Yeah it works but...
Thank you guys for your answers
Hm, okay. I hope Apple will fix these bugs with the next versions of Mac OS. Anyways, I think I'll go with a better iMac than I originally thought:
3.5 GHz i7
1TB Fusion Drive or 256GB SSD (not sure yet)
GTX 780M 4GB
I hope that's a configuration that will last for some years.
And it'd be great if you could send me your preferences
We have two of those speced machines with 512gb SSD's, 32gb Ram and they perform very well. I would go for the SSD as it is much faster than the Fusion drive (970mb read speeds). This will be helpful with disk caching, 4k footage playback and general io performance.
We have one of the 5k iMacs arriving Friday, I will let you know how they compare.
Okay, I now have my new iMac. As soon as my Adobe workspace is set up, I will post my experience here so that others might have a little help to decide which Mac to buy.
