will iMac 27" handle 4k red raw editing ?

iMac could be:
27" iMac Retina 5K
4,0GHz Intel Core i7, Turbo Boost 4,2 GHz
8 GB 1867MHz DDR3 SDRAM + 32gb 3rd party modules
256GB flash drive
AMD Radeon R9 M395X 4GB

will this setup handle raw (red raw from scarlet-x) edit and full res playback in premiere pro cc or fcpx ? anybody using same or similiar setup ? thank you

Why would you need full res playback for editing? I always turn mine down even if it can handle it. Reality is if you're editing in PP the viewport is only 1920ish on a 5k monitor anyways. What really matters is fast storage + good CPU and RAM. Get a raid array in there and you should be good.

i mean fullres playback like "full" in premiere preview window and not like 1/4 or 1/2 ;) my output is mostly 1080p at all so its not a problem but now with my GPU i cant handle full playback with some effect (for example procamp) and need to render after every change. GTX980 is not supported in PPCC2015.3 no change after add cuda_supported.txt even if Mercury CUDA is activated in PP settings GPU always running from 0-7% while rendering

The 980Ti doesn't work? That's weird my 780Ti renders layers of Lumitri and other effects just fine. Have you tried DaVinci? I think it supports more cards...

yes 780ti support is ok because of Kepler chip, CC cant recognize Maxwell chips. I was trying to render all GPU rendered effect (procamp,lumetri etc..) but gtx980 still idle and CPU goes to 100%. Davinci is just not my powerhouse but yes, working better with gpu sadly ...

Here's a thread from REDUSER.net that answers some your question with lots of detail: http://www.reduser.net/forum/showthread.php?147072-iMac-27-quot-for-red-...

There are many other threads there that talk about storage, the summary of which is that you probably want to buy SSD, not spinning disks going forward.

As for the Viewport on PP, one can obviously create a floating program window that's full-res for playback and not be constrained by the smaller windows of the default editing page layout.

i am using SSD for actual projects now, my problem is i need different GPU, current gtx980 cant handle full playback and for some reason bigger monitor than 24" making PP unusable - windows related but i cant solve it. so these issues and some more make me think to move from windows platform

Most people on the REDUSER boards are moving from Mac to Windows, because Mac platforms are capped at 2012-2013 technology levels. How many GTX980 cards do you have in your windows box? What generation of Xeon processors are you using?

Have one gtx980 but its not supported in PPCC2015.3 and gpu is constantly idle. Running with i7 5960x

A GTX980 should work just fine and is supported. The GPU will only do work if you have effects that are GPU enabled or if you are doing scaling. For regular rendering the GPU is hardly used or not at all used.

The 980 is nearly TWICE as fast as an M395X and Radeons CANNOT work with CUDA acceleration or openGL, so you're stuck with OpenCL, and stuck with that GPU for as long as you have the iMac. I'm a huge Mac fan but please don't make this move! If anything get a 980TI ... I'm running that in my Mac Pro and it KILLS with CUDA in after effects.

If you have some access to some .r3d files take them with you to an Apple store and ask if you can try to replay them on one of their iMacs.
Otherwise generate some Proxies (ProRes 422 LT in full resolution) and work with them.

Make sure you get raid to store everything.

If you're not in a hurry wait 1-2 months. Apple is gonna update their Macs.

I'm just about to take the plunge and move from 12C nMP to a PC. Even with the D700 GPUs in the mac, with Adobe not fully supporting GPU acceleration for RED playback, performance just isn't there. Unless Apple change tack at the next update, I'll reluctantly be reverting to PC.
