I'm developing an interactive 3D app in Unity that will be projected on a large curved wall and was curious what video card would best be suited to drive 6-8 projectors (most likely 6). I'm currently thinking of using Sony VPLFW60 projectors and my computer would be a Shuttle SZ170R8 System (i7 6700K, 32GB RAM). Would this be a performant configuration? Any insight or recommendations would be great. I'm currently looking at AMD FirePro W600 and NVIDIA GeForce GTX 1080. Would these options be appropriate?
The interactive app with be a 3D app, and it will be skinning meshes on the fly which will involve shaders. I looked into Unity's use of the GPU and it says that Unity will use the NVIDIA GPU for PhysX as well as for Shaders.
