Quote - What spec system do you have now, and what are you thinking of , also what version of poser ? 

I am using Poser 6 with almost exclusively the Poser 4 rendering. I am going from about a dual core 2.3 Ghz prosessor with 4GB ram and a crappy video card (I can only approximate because it died three weeks ago) to a 3.2 Ghz Intel core i5 650 with 8GB ram and for a graphics card a NVIDIA GeForce GT320 with 1GB of dedicated video memory. In order for this to be worth it to me it will have to be a very signficant speed increase, close to triple. Could I reasonably expect those results? From what I read in this thread it doesn't seem like the graphics card will make much of a difference.

That Octane program looks awesome! It is just too bad it doesn't seem compatible with Poser. Otherwise I would buy that thing in a second. That is the kind of results I would love.
