I have priced up an i7 770k with 4x 1080 ti 11gb ....not liquid cooled ..hope that won't be an issue.

Want to do animation of exterior and interiors ...could be very large ...interior of malls seems to be worst case.

I can see that using direct light might be the only option

Is it possible to do this kind of work yet on the system above or am I expecting too much?

I saw something about cloud render ...could this take up the slack in a tight situation.

I don't mind the look with direct light but excessive noise cannot be tolerated ....

Is anyone doing work like this ...so far all I can see is front living rooms and car type scenes but the real big architectural scenes are not shown at all?

Any advice would be appreciated at this stage before I waste any money or time exploring this avenue in depth ..

Thanks in advance...

Hi andy_vron,
4x 1080 ti are roughly up to ~760 in OctaneBench:

I'm used to do my animation in Path Tracing with less than 400 OctaneBench, max 3' per frame, so if you setup your scene correctly, you should not have issues with that monster.
Now with Adaptive sampling in Direct Light and Path Tracing, you can reaach high sampling in less time.
Anyway you can always use ORC that is great for animations and multiple results from the same scene, because the frames are spread on multiple nodes.
Happy GPU Rendering,
