The Octane demo I (re-)downloaded yesterday from the otoy site works decently in PPro2014, but probably will not address all its (new) features.  

I agree on the video-cards, the 690 (and 790 later this year) are just ways to crank FOUR 680’s / 780’s in a machine with just TWO dual-width PCI-16 slots available, and will put a drain on power and noise as well. Titan or even a 780 (70% of the price, 50% of the Vram) should do for Poser, more becomes handy when Vue rendering goes GPU as well (which seems a challenge to get the massive ecosystems into the limited amount of Vram)

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.
