Single GTX TITAN or Dual GTX 780Ti

What happens if you want to render ultra hires images? Is it still working, only segmented, or isn't it working at all?

if the resolution is so hign that You don't have enough vram, the render will fail & You'll not be able to do anything - so Vram does help if You need bigger resolutions.

thats very helpful info!
Can you please tell us what is the max resolution we can render with 780Ti with 3GB?
I am planning to render 4098x2160 resolution animation sequence, and my textures are approx. 1.7GB in that scene.

thanks

don't know for sure how to calculate & I can't look for numbers in program, 'cos at the moment rendering some tests.
For the record 8k Square seems to take 1.8GB of vRAM. So You should be just fine =)

I like to join this tech conversation. Currently i am rendering on a single GTX 780. The new 780ti with its 2880 cores is a bit faster. Does it make sense to buy another GTX 780 or can i take full advantage of the improved performance of a GTX 780ti in dual GPU mode?

You can take advamtage of all the power that is inside the card - I mean if it's faster You'll render faster - cards don't need to be the same. so in the end everything is 'bout the money You have to spend =)

Makes me wonder, too ... what happens if your scene needs more than the 3 GB I have on my 780Ti? Does it warn? stop? crash? swap? slow down?
