950W is plenty unless you're running a pair of old Nvidia 5xx cards.

Quote: V-Rays shitty shaders have nothing to do with whether GPU rendering performs better than CPU rendering and whether it will overtake in the future

It's not V-Ray's shaders that suck, it's that you don't get as much support for Maya's procedural nodes in GPU mode. Once you start to build more complex shaders with utilities like blendColors, multiply/Divide, +/-, sampler info, etc. RT GPU falls apart very quickly. It's just that making stuff work on the GPU is very difficult, so it takes longer to support. You won't get these types of shader nodes in furryball, Arion, Octane, etc. because they use a straightforward progressive path tracing ray trace and don't have a lot of flexibility (that's why all GPU renderers basically look exactly the same). If all you want is a quick preview of some metal or car paint materials and a sun/sky, you should be fine but if you're looking to do out-of-the-box VFX stuff, leave GPU rendering out of the equation. The GPU can be really handy for certain things but it's not a one-stop shop like the CPU is.
