Any advice as to which setup would be more beneficial with Octane?
Considering the change over to the single 1070.

hi,

1070 are still not supported. Speed wise single 1070 is probably goign to be slower than 2x 780Tis, but you gain more usable vram. So it depends..

Few years ago, when I've started with Octane I've jumped from 2x 460s (1.25GB) to 670 (4GB) SKU, without gaining any speed - this is sort of the same situation.

Less noise, less heat & additional slot left for upgrade might be another good point, why this upgrade might be worth to consider, but speed wise it would be slower.

I really think most folks must end up regretting buying 70s, 60s (I've seen plenty here) when they are doing even a modest amount of GPU rendering. IMHO, never, ever, buy anything less than 80 or 80Ti. If you make money (at all) with your workstation, you'd be doing yourself a major disservice getting 70s.

Thanks I think you've convinced me. It's better to just add additional 780 ti to fill out to 3 or 4 sli etc.
As I could get them for the same price as the 1070 plus considering your advice with not yet being supported. Down the road I'd replace all 4 for two brand new cards which by then will be better than the 1070 or 1080. Cool. Thanks.

Found a seller for two more 780tis . I'm looking forward to seeing what 4 Gpus can do :)

I do strongly aggree with FrankPooleFloating

Have a grasp on nVidia`s marketing strategy.

70s are always 20-30% low on price and in performance.
Ti`s are always 20-35% high on price and performance.

Think about how much PCI slots you can handle on your motherboard and consider Octane license fees.
Consider powersupply and cooling prices (I did not include chasis price)

If you don`t need multi-GPU, buy 70s of the supported generation.

If you are in a situation like me, to render about millions of frames, use 80s and even Ti`s of the same line

(Ti`s cost less when compared to put them in a single motherboard but in long terms of rendering, energy costs meet and exceeds the balance)

Always use benchmarking and trust Octane Benchmark results, and try to understand them. They do work perfectly.
