I spent ages on AMD's website yesterday and did not find what I was looking for (despite using the site's search box and Google), this evening I again clicked on the link I posted earlier, used AMD's search box (again), and out pops this:
and a bit more detail:
A couple of minutes digesting that, and I now realise that I want an X570 motherboard for the 5950X CPU (that I have already purchased).
Before anyone asks, I decided not to go for Wootware's R9 custom build because the only option available to change was the graphics card, and for a start I want 2 * 32GB of DDR4, but there's no way of changing that on Wootware's site. I also have no intention of letting Windows control my hardware (100% Linux).
It seems like DDR4-3600 is the way to go, or DDR4-3200.
I'm not sure which direction to take as far as graphics cards are concerned (it's not for a gaming rig), price and availability will likely dictate, but I do have somewhat old FreeSync monitors. So maybe Radeon instead of NVidia?
Although I have survived without FreeSync until now (again it's not for gaming), I also have no idea if my old FreeSync monitors would even be supported.
Water cooler for the CPU, what should I avoid/consider there?
I don't give a pile of rat droppings about RGB on any fans, memory or other components (RGB lighting is annoying enough on keyboards and mice).
Any advice still welcome.
