Is it as simple as "versus Firefly, Octane will give you more accurate renders and Lux will give you faster renders"?  That's what I really need to know, comparisons of quality are largely moot if I'm currently content with Firefly's output.  Still not seeing much information on how these renderers handle heavily displaced geometry.  Surely there are some sacrifices to be made to achieve these gains?

Octane is the fastest unbiased renderer.  The only sacrifice is that you are limited to 144 color texturemaps and 68 b&w (bump/trans) maps and you need a compatible graphics card.  Plus texturemaps have to fit in your graphics card memory (seldom a limitation on a 2GB card and with 3GB not a limitation).

There is a good independent Lux verses Octane blog entry on Deviart (link to it from my facebook page below).  I think they are both great rendering solutions for Poser.

heavily displaced geometry.

Are you referring to displacement maps or actual displaced vertices?

Would two 660ti cards compare to a gtx 670, or would that card's higher RAM be more useful?

My understanding is that a 660Ti card provides almost the same Octane rendering speed as a 670, and is a much lower cost.  According to the Octane benchmarks, a Titan is 3.65 times quicker than a 660Ti.
