Best 1 or 2 graphics cards for max performance?

I am looking at one or two cards for max performance. 
what is the best choice for maximum rendering speed. Starting with lowest price. For example some lower level cards are cheaper but have more cuda cores so maybe buy 2? Look at GTX780. Lots of cuda cores. What am I missing?

I heard prob the most important thing is cuda cores.


Thanks

    RAM also matters - no matter how many cores you have, if the sceen won't fit into the card's RAM they won't be used. Cores are not necessarily equivalent across generations, either.

    With new 10 series now working with daz studio beta your best bet is a 1070 or a 1060 because of the 8gb of video ram. If you can find a good deal I would recommend purchasing a titan x which comes with 12gb of video ram. If you are on a strict budget I would wait and get a 750ti 4gb edition when onsale under a hundred dollars. Yes the 780ti has alot of cuda cores but it only has 3gb of video ram if you can find a 6gb edition for really cheap under $200 othewise just get a 1060 or a 1070 they are both worth the money and time they will save you. Oh as a side note I am running one 1070 founders edition to run my multiple monitor setup and 3 780's 6gb editon Nvidia graphics cards and they work great together on a Intel i7 x79 system with windows 7 pro. A warning tho if you start messing with mulitple card setups (more than 2) you are going to need 32gig of ram and a 800 watt or greater powersupply.

    The Titan version of the 10 series card; seriously expensive though.

    The 1080, again seriously expensive, if less so than above. How much faster than 9 series cards is open to debate atm. Rendering support is a few days old.

    A card with 4GB of RAM should be considered the minimum but not decent minimum. IMO 6GB is the minimum to consider. This does however depend on your scene type; one figure, not many clothes, and as simple background will easily fit in a 4GB card.

    The above is for cards not also used for display. Discount the card used for display; as it will have less RAM available to use; useful when it can be added to assist, but it will also make the computer seem sluggish.

    i own a 780 so yes, it works quite cell.

    I recently bought a 980 TI.

    If i must compare both : the 980 TI is kiilling it. It only has 500 more cuda cores so i expected it to be a little faster but the truth is is at least twice faster and i don't have preview mode lagging anymore.

    As for your question about 1 or 2 gpu, it think it dependsg on your screen resolution and the number of screen you use.

    I use 2 monitors and one of them is uhd (3200*1800) so the best for my case it to have 2GPU : 1 to drive the screens (GTX 780 n my case) and the second one that does all the rendering (GTX 980 Ti).

    Display uses VRAM, especially big resolutions so if you have one GPU only, some of your VRAM will be used for display so big scene won't fit in your VRAM anymore, even if you have 6Gb of it.

    This is what happens when you use CUDA cores to compare different generations of cards. :)

    More is better, but across generations, other factors come into play and need to be considered.

    This posts a bit old now but I was discussing a similarissue recently, you may find this article interesting regarding multi card setup speeds and IRAY - https://www.pugetsystems.com/labs/articles/NVIDIA-Iray-GPU-Performance-Comparison-785/

    this is a good source for base info on the cards.. and it shows pricing to performance value.
    ---
    it shows the 980ti at about 50% more performance than a 780 ...
    ---
    I have a 980 ti with 6 gigs and haven't bounced off the card yet...
