Hi, actually, darktable profits much more from OpenCL support than from better CPUs/more cores etc.
If at all possible, try to get OpenCL working. This involves cards from NVidia or AMD, and using their closed-source drivers. The NVidia drivers are traditionally better at continuing to support older hardware, while people on the list had AMD drop support for their reasonable middle-aged card. On the other hand, there seem to be more creative ways to get a half-installed AMD driver to work on systems it is not intended for. I'm happy with a NVidia card (750 Ti, 2GB RAM), used with the boring closed-source driver, this makes a huge difference on my aging quadcore. If I get your proposed configuration right, this might mean installing a 4GB gaming graphics card on a headless system -- I think it is worth it. But I wonder if it is possible to get the colors right on a TV, is calibration possible for a TV backend?

Just an example, see what happens on my PC when I browse a collection of RAW files in darkroom: lots of threads and CPU core being used: https://imgur.com/a/cSNac Currently I own an aging 4-core AMD so I'm thrilled about the new Ryzen CPUs, too.
