Lol, I oh don't have any plans to run Octane on my current rig  :)  As far as I know, it can't be done (maybe someone with tech expertise to build laptops from scratch could somehow do it but it's beyond my current skill level).

On the other hand, I am planning at some point in the future I'll need a new rig anyway (my laptop is 2 -3 years old now, and works just fine, but nothing lasts forever).  Next rig I get, I'll be factoring in the possibility of GPU rendering into the equasion (I don't necessary feel the need to get a Titan lol, but it would be nice to have one of the lower priced Nvidia cards so I have the option).

Assuming my current laptop doesn't unexpectedly die on me, I probably won't be looking at getting together the new rig until middle of next year at the soonest, and who knows the whole landscape may have changed by then. 

When I first started seeing renders from unbiased renderers I decided I had to have an unbiased render solution.  Octane was too much for my laptop and Lux was too slow, so I've picked up Thea, and I really like the quality of the renders.  I'm not saying Unbiased is better than Biased because I feel they both have their strengths, and for most circumstances I can render full GI using Carrara's biased renderer and it works for what I need, but there are other circumstances where only unbiased will do, so I think it's good to have both a biased and an unbiased renderer in my stable so I can call upon the 'right man for the job' when needed.

The Luxus for Carrara plugin works pretty well, even better with the newest release, so I'm going to keep refining and learning how best to texture with it, and I'm aware there is a GPU version of Lux now.  There's already a GPU version of Thea, and soon to be a CPU + GPU version, so even if I never get Octane, I can still safely say that at some point in my future I'll want to have a computer that could do GPU rendering, which is why this topic is of such interest to me.

Now the laptop I have works fine, and the renders in Thea don't take very long, even though it's CPU rendering, neither to the renders in Carrara, and of course I could simply say 'good enough'.  But I think it's only human nature that we all want our renders to be faster, as fast as possible :)  This is why I'm 100% behind the idea that DAZ should incorporate Embree into Carrara to speed the rendering, and why I'm also eager at some point to upgrade my machine to be able to take advantage of GPU rendering technology.  Hell, I think even if we all got to the 'rendering singularity' where every program could render even the most complicated image in only 1 second, we'd all be complaining about how we wished we could get our render speed down to half a second  :)
