Hello , I currently have 2 GTX 690 2GB....
I'm thinking to invest on a GPU card but I haven't checked what are my opinion according to Octanes demands . I haven't bought a GPU card for a long time now.I know that octanes needs COREs and memory but I don't know which card supports better the software for best speed performance.... I'm thinking GTX 1070 or GTX 1080 with 6 gb or the TITAN X with 12GB ...dose octane supports this type of card ? Thanks
GPU suggestions...

I don't mean to be rude but there is like twelve post about the same thing in the forums just this month, aren't there?
You are right about that Octane needs cuda cores and memory, generally speaking the more cores you have the better your render speeds will be and about the memory, you just need enough, there is no reason to get an expensive Titan X for 12gb of ram if you are never going to fill those, not used memory is wasted memory.
You also want to keep in mind the amount of cards that you are going to be using, the cooler they are the better, cards when they get hot they under perform. So if you are going to use just fans you want to consider a setup that will let them be apart from each other like those cases that have them hanging. Most people here in the forums will recommend you to go for some sort of solution based around water cooling and give the cards plenty of power with a good PSU.
The latest built of Octane can run on the latest gtx10xx series, my knowledge is that there is still some room for optimization using this architecture but the general performance is still better than the last gen.

Terry is right.
What I may add: 1st step - sell all your 690 - these are power hungry cards. 2nd step - get 4x 1070 provided they are at least hybrids (unless you like working in a very noisy environment and don't care about speed loss on an aircooled 4 gpu setup due to heat). Otherwise get 2-3x 1070, but 3x 1070 only when you have a motherboard that has a "middle" pci slot to give you extra space between all 3 gpus.
