I am looking to see what Octane builds people are using before I start on my Own.
I am currently looking at purchasing either 2 GTX 750 Ti

Or a single 760

Given the choice, I'd go with the 760 X2 without a second thought. It has 2304 CUDA Cores, vs 640 CUDA Cores (x2 =1280) of the 750 Ti, and the 760 has 4GB of 512-Bit GDDR5 RAM vs. 2GB of 128-Bit GDDR5 RAM for the 750Ti (note that per card RAM doesn't add, you are limited to the max amount of RAM on the card with the LEAST amount of RAM). The 760 will be a MUCH better card for Octane, it's faster and has more RAM (right now you are still limited to the RAM on your video card).
Hope this helps.
PS: Given the price of the 760, I'd actually go with this 780 with 6GB of RAM http://www.newegg.com/Product/Product.aspx?Item=N82E16814487040&cm_re=gtx_780-_-14-487-040-_-Product
Eventually, you're always gonna regret not going bigger and better. I've got a GTX 690 and a small part of me still wishes I had a Titan (or two).
Last time I tried 750 Ti Octane didn't recognize it. But I haven't tried it with version Octane 2.0 maybe they fixed it ?
From what I understand, the 750 Ti works with the latest version of Octane but not with the current Daz plugin as we're still waiting for the update.
Thanks you I'm putting in my computer tonight !!!
I purchased a 750 Titan, the Octane Render, and the DAZ plug in based on the same faulty information. (I.e. the base renderer worked, so the plug in should.)
It didn't. When I inquired about when the plug in would be updated I got "when it's ready." When I asked when it would be ready, I got "it's ready when it's ready."
I returned everything but the video card. After minimal arguing with Octane, I got all that money returned.
I am using an ASUS DiirectCU II GTX 780ti with 3Gb for rendering and an ASUS DirectCU II GTX 670 for driving my two displays. This works very well. 3Gb of VRAM are working out fine for my purposes. I like the DirectCU card because of their excellent cooling (direct copper contact, big heat pipes and a heat sink) which makes them run very quiet even under load. My motherboard has space for a third card and I am contemplating adding another GTX 780.

Hello
You frequently checks with the temperatures of your 780?
If yes, how many degrees your gtx reaches when rendering in octane?
At first, I freaked out when my ASUS gtx Titan reached 76 degrees rendering in octane (Octane demo version for now ...)
I did some research on google and found this is normal in serie 780/titan
it looks like a titan gtx can reach 85 degrees, standard factory
But I confess that I thought something was wrong ...
Someone told me that the titan it also reaches 76 degrees when he's playing
In my case, when not using octane, the titan gtx temperature is between 27 and 29 degrees
They brought a gtx 780 to my shop that was over heating, I opened the fan mount and applied some new thermal compound and that did the trick.
You say the reference model?
this video card that you mention, is not single, not:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814121839&cm_re=gtx_760_4gb-_-14-121-839-_-Product
is a dual GPU
A few months ago when I questioned the team Ocatne Render on the performance of a gtx 690
They answered me:
""Hi, Thanks for contacting us.
The 690 is indeed two GPU's on the same board. By default SLI is enabled for this GPU and it is best to disable it for Octane. The confusion might be about exactly what SLI is. SLI has been given the labeling of "multi-GPU" because for gaming, this is the only way to get both GPU's to work together. It is a technology for gaming, not for CUDA (general compute).
For octane each GPU is exposed as a CUDA device, it does not need to make use of SLI to use both GPUs on the card.
Hence, SLI is best turned off for octane, because it might interfere with using each GPU as a separate device, and is for Gaming only. So in short, SLI is a gaming technology and is not needed for octane to use multiple GPU's or cards. Thanks
The OctaneRender Team"""
But right now I do not know the new version of octane ... that can be changed
There is also this one http://www.newegg.com/Product/Product.aspx?Item=N82E16814127748
I also agree with you
yes this is really an ideal single for octane
Yes, yes this is a single!
it also seems to be the most affordable option.
The reason I wanted to get two gtx 750 is it has a 5 on the Compute Capability.

Hi!
The GTX 780 runs at temperatures in the high 50s or low 60s when rendering under full load. On a hot summer day it can go up to the low 70s. That is at default clock speed. If I overclock it gets much hotter. I should point out that my system is built into a very large case (Corsair Obsidian 800D) with 8 performance fans and a liquid cooler for the CPU. That keeps things pretty cool and quiet. Temperatures in the 80s are typically not an issue for a modern gaming card, but cooler is better and extends life time.

Thanks for the tip about disabling SLI, Jorge. I wasn't aware of that.
Am I correct in assuming I just have to "disable multi-GPU mode" in the Nvidia Control Panel?
Well, I do not have a gtx 690, no.
but I believe the process is this:
open NVidia control panel > click on set physx or configure SLI option > user will see option to disable SLI

Hmm, low 60 degrees? I really wish my video card temperature dropped to this level, too, but ...
my system is only cooled on wind
...so they have a GTX GPU (Titan-Z) that has more Cuda cores and as much VRAM as a Quadro K6000 now. Interesting.
As far as I know, the Titan Z is really two Titans on one board, i.e. a double GPU, so you do not have 12G , but 2 times 6Gb with twice the CUDA cores of a standard Titan. On the other hand, the Quadro K6000 has really 12 Gb of available vram, but only a single GPU and hence less cuda cores.

Yeah ... I have already got used to living delayed / lost behind in technology ... And here in Brazil, it is still a third world country ...
I could buy a basic titan 2688 Cudas, because she is losing place for titan black
The titan black is high here in Brazil now
as the titan"Z" so far seen only 3 vendors selling in Brazil
one unit each ... I think it's the first shipments that are coming in Brazil
But I could be wrong, please correct me:
Titan Z is a dual GPU
Octane render will only use 6gb of Vram, the 12gb Z

No, you are completely correct as far as I know. That's what I also posted just above your post.
TD
No, you are completely correct as far as I know. That's what I also posted just above your post.
TD
Oh yeah!
At the moment, a Titan Z in Brazil can cost the price to R$ 13.165,00= USD 5.933,00

...so if you have the resources. the K6000 is still a better choice because of the total VRAM available and because it requires less power (runs cooler) as it is not overclocked.
Good to know.
Also Quadro GPUs are generally more ruggedly constructed as they are required to handle peak loads over long usage times.

...here in the US the Quadro K6000 is about 4,900 USD,
If your looking for a less expensive card, the one you linked to here looks great. It will have good performance, and a decent amount of RAM to work with. I tried this scene (warning - nudity http://www.renderosity.com/mod/gallery/index.php?image_id=2260952) in Octane 2.1 with a 3Gb card, and almost all the textures loaded (3 V4's, 3 M4's, Faveral's Medieval Docks, and some extra props). If I reduce the M4 textures to half resolution, I'm sure the everything would have loaded. This should give you a good idea about how much you could fit into 4Gb of RAM (this scene would have easily loaded in 4Gb).
...pretty nice.
Imagine what could be done with a full 12G (that is as much memory as my current workstation has).
True, 5 grand for a GPU is pretty steep however for the complex scenes I tend to create, I'd need that much "horsepower" if I were to go the route of GPU rendering.

Yes, and no ...
Nvidia Quadro K6000 12gb = CUDA Cores 2880
Gtx Titan Z 12gb = Cuda Cores: 5.760 (2880 por GPU)
Recalling that
The issue of Octane in DUAL video cards, it is only with relation to the memories of both.
But not with relation to cuda
you can put 2 different video cards in your computer (gtx 560 + gtx 690), octane will use the memory of a video card only, but will use all cuda cores of both ...
one gtx 690 with dual disabled will use the memory of the first video card only, but will enjoy all the cuda cores.
in a Titan Z, Octane will use 6GB of memory only, but will use all cores Cuda 5,760 (2880 for each GPU)
That is not quite right. You can use two different cards, but Octane has to use the VRAM in each card which means that the card with the lower amount of VRAM determines your maximum available VRAM. For example in my system I can use both the GTX 670 2GB and the GTX 780 3GB for rendering at the same time, but then my max VRAM will be limited to what ever is available o n the GTX 670 (about 1.5 GB because it also drives the displays).
