"You can do a three character scene with HDRI lighting and background in well under 10 minutes with a reasonable class machine (NVIDIA 7 series card and up, Quad I7 processor, and at least 8 gigs of RAM).
As soon as you start adding scene geometry, the time goes up significantly since all that bouncing around of light takes time to calculate. I can't get an indoor scene where all the furniture and walls are geometry to render in anything less than an hour with a dual quad core I7, 72 GB ram, NVIDIA 970 card.
When the scene gets complex enough that IRAY has to fall back on CPU processing because it all doesn't fit in the RAM on the video card, things slow down significantly."
Is that a typo or do you really have 72GB of RAM? Holy s###! What kind of machine do you have?!
I bought a used Dell Precision T5500 on E-Bay for $350 - two quad core I7's. Basically a workstation server. Added the 72 GB of ram for around $600 to max the machine out. Recently stuck the EVA NVDIA 970 on it for $320, and it has two 2 Terrabyte hard drives at $80 a piece. So all told I have around $1,400 dollars in it. Five year old equipment can be pretty awesome if you go about it right.
