I thought I'd test a small animation using the iRay plugin as a rough guide for anyone that may be interested.
My system is as follows:32.GB RAM
Intel Core i7-6700 3.4ghz
Win10 64 bit
nvidia 1080ti - 11GB
Animation Length / Output: 1800 frames / 19 seconds
Rendered with IBL Lighting
Custom Avatar has 2k PBR textures
Output Resolution; 1920x1080
Sample Iterations: 1000
FPS: 60
Total Render Time: 14 hours
