system requirements

There have been several discussions on this in recent weeks. You might do a quick search of the forum and review the arguments discussion. 🙂

Of the Adobe suite tools, though, InDesign is among the least demanding. It uses only one CPU core, so the number of cores you pay for will be more relevant to Photoshop, AfterEffects, Premiere and things like games. Any i7 CPU should be fine; one that's a little further up the power spectrum would not be money misspent. (That said, I am in the camp of buying at the "moderate" point on whatever the current CPU curve is; at the top of the peak, but not out on the leading edge where prices triple for power increases not generally proportional to cost.)

RAM is crucial. Most modern apps (and games) really demand 32GB for most purposes. 64GB is overkill unless you're going to work with very large Photoshop and AE projects. But 16GB won't really do it any more.

Fast SSDs are essential as well. HDDs are no longer a good buy except for bulk storage of things like video projects and archives. You want a fast SSD for boot, apps, scratch disks and working projects. A second SSD for project data files is a nice thing to have.

Video: almost any system with a name-brand video adapter (Nvidia or AMD) is good enough for InDesign. You will want the ability to drive an external 4K monitor, and (again) for the more power-hungry tools, a GPU that's up the curve will be a nice asset. InDesign does not use GPU acceleration (under Windows), but some of the other apps do. (Teh jump from no-GPU to modest-GPU is MUCH larger than from modest-GPU to mega-GPU, though, so don't go overboard unless you're going to dock into multiple desk monitors.)

Decent i7. 32GB RAM. Two SSDs with 2-4TB each. Decent name-brand (that means not "Intel Business Graphics" or some such) video adapter. At least one video port (DP or HDMI). That'll do ya.
