Purpose built mini ITX?

I am considering building a Mini ITX computer with the sole purpose of modeling in Sketchup and when i can afford a license rendering in Lumion. My previous work had a beast of a workstation with Lumion and it rendered pretty well. Its specs were...

X79 Mobo
i7 3930k
64Gb 1866 Ram
360Gb SSD
FirePro W8000 4Gb

My main concern is the memory with the ITX build.

This is what i plan on building.

Z97 Mobo
i7 4790k
16Gb 1866 Ram
128Gb M.2 SSD

I know that everything is better and faster than the previous build except the Ram. How much will that affect me for video processing?

I do hope you will be able to get a Lumion license soon, to go with your SketchUp.  Don't forget you have the option of Lumion at lower entry price, or Lumion Pro.

- 16Gb RAM for Lumion is fine, for SketchUp?  Maybe more is better, say 32GB.
- A 128GB SSD is really too small, especially for Lumion files stored under \My Documents unless you redirect My Documents.
 - The GTX 780 has some good performance results and Benchmark, overclocked version seems to be close or matching GTX 780 Ti's (sample only one recent purchaser).  Having 6GB has means you can do more.

Does Lumion use the memory for any part of image or video rendering? Or is it all up to the GPU. I would really like to see the score that the 6Gb 780 puts out in Lumion. When slightly overclocked it puts up the highest single GPU numbers i've seen (not counting workstation cards).,25.html

Lumion uses the CPU and RAM for managing and storing the rendered video frames and doing the final compression to MP4.

Not sure yet if any of the Ti's are overclocked as the clock rates are already increased by NVIDIA.
Always of course a little risky running long period OC graphics unless have good cooling systems.

See Benchmark topic.  Range ofr GTX 780 is 17640 to 22140.
