for nVidia Octane comunity is too small to care too much..however they made some nice tools, polished their CUDA for programers/developers to pick up and go - it was their investment & it worked out for them, as CUDA is videlly adopted..
now a lot of talks about support of AMD cards, however they do run hot,..noisy & so.. - the prise will always follow the demand..- as miners jumped into GPU computing, some models from red team were jumping in price quite a lot..
for some reason I'm quite skeptic 'bout this jump, but..who knows maybe it will be good thing for OTOY & comunity.
