Hi,
Have anyone tested 3x gtx 1080 packed close to each other on boards like sabertooth x79? I need to build a new rendernode using spare parts from my old PC and i am thinking about buying 3x 1080 or 3x 980ti. My concern when buying gtx 1080 is that it has not been tested enough and i need stability on my commercial projects. 3x 980ti might get too hot but 2 of them considering how much space would be left between them would be ok. The build will run on air.

We know almost nothing about 1080 performance in Octane. It may be 20-30% faster but it price is also 20% more to 980ti.

For now the one & only advice 980Ti (as Sebastian mentioned, 1080s do not work just yet).
980Tis are fine in multiGPU environment, even if they have no extra gaps just get reference desing cooler equiped cards or even better look for AIO equiped hybrid solutions.

I currently run 3x MSI 980Ti's with stock cooling with no issue.

Thanks for the help guys, i will go with 3x GTX980ti for now. I am also thinking about changing my 2x TitanZ build to 7x GTX980ti, if anyone is interested in my TitanZ cards with water blocks let me know.

Piotr, I'm curious what's the point of upgrade? 2x TitanZ (cards) would give you what.. up to 220 each (110 per single gk110 based GPU) under watercooling, while 3x 980Ti 3x 140 (OCed) I mean what's the point of of upgrading? (wasting additional slot), getting the same amount of vram & the same speed. Kind of hard to understand..
please read again!
he's getting 1 pc with 3x980ti and is replacing graphics cards in 1pc currently equipped with 2 titanZ to be changed with 7x980ti...
I wonder what kind of board and power supply supports 7x 980ti, though.

OU I missed & 7 GPU part (thanks for poinitng).
7GPUs are supported by high end X99 with PLX chips (like asus x99e ws or asrock x99 ws-e) or dual CPU boards..
PSU wise, You can lift of with 1500-1600W but more would be recomended =)..
