Have need to build a new desktop computer to be an Ubuntu operated machine. Thought it wise to seek advise regarding either components that are more or less desirable as well as the possibility of those to avoid.

Particular concern pertains to how long it takes Ubuntu in particular (Linux in general) to incorporate support for new products/features. In that, what is the risk of acquiring new, most up to date, products and finding that they don't work so good with Ubuntu/Linux. For example, Intel now marketing something called Optane Memory which I suspect is not supported by Ubuntu/Linux.

Instinctive preference is for Intel processors & chipsets but could easily be persuaded to do something else for good reason.

A known use for this computer would be digital image processing using software like GIMP, Rawtherapee, Darktable, etc. This particularly involves the need for display calibration. In choosing graphics components what needs to be considered? Integrated graphics seem like the most straightforward approach but would like to know if there is a good case to be made for doing something else.
