including the GPU memory I say it's insane :) -- Also, you need more than 32GB of RAM to follow the instructions verbatim in the repository. People were saying the scann indexing fails even with 64GB of RAM.
128GB = 4x 32GB DDR4 UDIMM costs less than 360€.
That's a lot less than the GPU.
Yeah they're technically cheaper than a GPU, but your costs are still gonna be up and they can't replace a GPU because regardless you'll need an nvidia card, unless there's a workaround for CUDA requirements.
