Is CO 8 RAM intensive or CPU intensive?

Hi, I have a older late model 2009 iMAC i7, 8GB ram, not sure of graphics card.

I am considering upgrading because: 1) Purchased a 5DS and I have used up the 1TB drive and 2) notice a log in processing 3) looking forward to 5K monitor.

Question: When customizing 27" iMac - What should I put the most money into: RAM or CPU?

Currently looking at the latest 27" iMAC 5K with 3TB drive, 16GB RAM, i7 quad.

If it's CPU intensive is the one quad enough for CO8 or do I really need the Mac Pro?

Starting to notice a lag in the processing of these massive 5DS 70MB files?

thanks,

  While both are important, if you are looking to spend extra, I'd suggest you'll get better performance gains from an SSD drive, and a better GPU.

  I have a mid-2011 iMac with 20GB of RAM. C1 hogs both CPU and memory resources. If I were to upgrade I would get 32GB of RAM or more and the fastest processor I can afford without putting myself into too much debt.

  The more power you give CO the better, that's the buttom line.
  
  4k-5k monitors will slow down preview generation, which will in turn slow down browsing, import and tethering.
  
  I would recommend the Mac Pro as is has faster GPU's and has more cores on the CPU, if you are professional, using CO day in and day out.
  If you are using it occasionally instead, you can probably live with the performance of the best spec'ed iMac 5k.

  I am not using Mac, but PC/Win and from what I see CO8.3.* is rather CPU/GPU bound - I never had issues with memory shortage on 32GB ram (not using any swap/virtual memory to HDD/SSD and having PS opened at the same time and other applications)... my raw files are 24mp though - may be with some 80mp+ or multishot raws it is different, but otherwise 32Gb is OK, I even had dedicate some of that towards RAM disk for temp. files (that is 10-100 times faster than temp files on any SSD)

  Thanks the for insight Christian.
  
  The iMac 5K has an optional Graphics card with 4GB RAM instead of 2.
  I am non-pro user, but very picky on image quality and don't like waiting while sitting at computer. I don't have deep pockets either.
  
  I will settle on the iMac 27" 5K at some point when I see a sale, LOL.
  
  I opened up system monitor and fount RAM is not used as much as CPU and other graphics memory.
  
  thanks

  4 gb of VRAM vs 2 won't do very much, unless you use a lot of GPU intensive applications at the same time.
