Well, that cost of the systems, plus operating systems, will set you back around another $3,000 and you'll have some slowish processors. For the same cost you could have 8 Titans or 12-14 GTX 780s, which are nearly as fast as Titans in Octane. I think I know who wins that battle.
Octane is very inexpensive and if you do build up your gpu capability it has the advantage of bypassing NET which is often a PITA, plus you have the near real-time feedback. OTOH, there are some significant limitations (limited multipass, motion blur, sketch, hair, shaders, etc.).
I've just started out with it but I'm liking it a lot. It scratches that unbiased Maxwell itch without the interminable Maxwell render times.
