Graphics card upgrade advice (duel 980Ti to duel 1080Ti)

in Technical Help (nuts n bolts)

I currently have a system with 2 x NVIDIA GeForce GTX 980 Ti and am suffering from some pretty annoying render times on some scenes (up to 2.5 hours) and would like to get that down.  So am considering the natural progression of putting in  2 x NVIDIA GeForce GTX 1080i Ti.

I have two questions on this:
(a) I assume people have done this here, roughly what kind of realistic render improvement are we looking at?
(b) There appear to be lots of different types of 1080Ti cards out there, does anyone have any recommendations or are they pretty much all the same?

Other system stuff if needed:
Overclocked Intel i7-5820K Processor
Asus X99-A Motherboard 
64Gb Ram
2 TB HDD, 7200 / 480 GB SSD

Thanks
Lee

    2.5 hours for rendering a complex scene is pretty good. Ther are things you can do to shorten the times further.

    How about posting a screenshot?

    With a pair of 1080ti's you could expect perhaps 35% less render time, maybe a bit better. What you be able to do id render much more complex scenes due to the increased VRAM

    I'd say you're better off just adding a single 1080ti to your exisitng 980 tis, assuming your motherboard has the slots available, if you can deal with the 6GB ram limit.
