Achrviz on render farm or videocards stack

Hello, can anybody help me with render farm creation or vcards stack.
While working on the project, I lack the power of my video card. Please advice professional solutions for creating a farm for rendering architectural objects in UE4 with raytracing.

UE4 cannot take advantage of multiple graphics cards currently

Innokentius89…have you had any luck with this in the last couple years? I am in the same boat. Looking to develop a render farm video card stack.

Thanks

Hey what exactly do you mean with render farm? Something like SLI to use multiple video cards to render a scene in real time or move the viewport camera around during editing or are you talking about a render farm that builds lighting for you?

Yes realtime renderings. So SLI or a Render Farm Stack of video cards. Not interested in building lighting in this instance.
