I'm about to replace my ageing desktop PC and think I should base its configuration on Lightroom's requirements as that probably requires more of everything than anything else I run.
My only restriction is that I'm a lifelong PC, not Mac, man. I'm looking at CPU, memory, disks (SSD,hard,optical) graphics, input devices, monitor, external devices etc. Whatever you consider important.
So, what guidance can you offer me?
Thanks for your time
Get 8GB of memory or more, and the fastest CPU you can afford. If you want a really large monitor (4K or 5K), you need a modern and reasonably powerful video card (please read Adobe's specs regarding video cards). An SSD that is large enough for your catalog and previews (and anything else you want to put on the SSD) is helpful.
All the rest is personal preference.
