... not what you asked for but since I use for the most part renderers, which need CPU power in particular (such as Shaderlight, ArtLantis or RenderIn) this machine would be a dream for me.
Although the core clocking is not the fastest one this amount of 16 (32) cores would compensate that.

Perhaps you intend to use such other renderers parallel to Vray as well, this would be an excellent setup and the price is super...
