Which NVidia Titan?

I'm slowly working my way toward the purchase of a Nvidia Titan card for use with either Octane Render, Luxcore, or both in Carrara 8.5 .

A few months ago the price of the Titan Z dropped from $3000+ to $1600. This cought my eye. As I understood it, this was like getting 2 Titan Black cards in one physical package, amost twice the number of Cuda core processors as the Titan X, more shader cores and wider buss path. Hmmm.

Getting closer to pulling the trigger I now see the Titan X is around $1000 now but pulling better benchmark scores, but has less Cuda's, shaders and buss width. Renferece: http://gpuboss.com/gpus/GeForce-GTX-TITAN-Z-vs-GeForce-GTX-TITAN-X

Can anyone who has Octane, Luxcore, or both please advise... would Titan X be just as good... or does the Z card warrant the extra expense?

Thanks in advance.

    Go for the Titan X, it has 12gb of vram legitimately. Titan Z is two 6gb drives combined into one so it can only access 6gb if I'm not mistaken. I currently run superclocked Titan blacks and they are amazing in Octane but I wouldnt suggest buying the black now that tian x is around.

    Here are some benchmarks of both, including LuxMark:

    Because of the 12GB memory and Luxrender only being able to render in GPU VRAM, the Titan X is the one.
    Octane just recieved support for CPU RAM rendering, but it does take a performance hit when using it.
    It is also easier to include a second (third or fourth) Titan X, since it is a single chip card and needs 250W, while the other needs 400W and is a dual chip card.
    Good luck!
