I am planning for a i7 10700k and saw the other post about Intel non-k. I want 32Gb of RAM for my next build (Gaming PC with nvidia RTX2080 and 4k Monitor, I have not yet decided on a motherboard).
I read CL should be 16 or lower but I am not so sure how important RAM speed is. Sometimes you read the higher the better, some time you read too high can even be counter productive.
For around the same price I could buy 3000-CL15 or 3200-CL16. What should I prefer or is it even worth to spend (a lot) more money on 3600-CL16? Should I prefer a 4x8 or 2x16 kit?

The kits I would probably choose between without further advice are:
32GB-Crucial-Ballistix-Sport-DDR4-3000-DIMM-CL15-Dual-Kit or
32GB-Corsair-Vengeance-LPX-DDR4-3200-DIMM-CL16-Dual-Kit or
32GB-Crucial-Ballistix-PC-3600-CL16-KIT--2x16GB

Oh, and one more question:
The 10700K supports "Memory Types DDR4-2933" according to Intel specifications.
Wikipedia lists DDR4 RAM to end at 3200. Does this mean everything above those values means overclocking my memory bus?

It will depend of your motherboard choice. S
If you pick a B460 chipset you will be limited to 2933 Mhz, but on a Z-490 MoBo you will be able to use higher speeds. Exact value depends of the exact MoBo choice.
So a kit like like 32GB-Crucial-Ballistix-PC-3600-CL16-KIT--2x16GB only makes sense on a z-490.
Moreover each MoBo has a QVL, which is a list (L) of tested models of RAM sticks that work at a certain speed on that particular MoBo

ok, thanks, I think a Z-490 is within the budget and good for other reasons anyway and I will check the QVL. But let’s say I find compatible RAM.

-Does 3600 RAM really have a strong benefit that is worth the high price?
-Is a bit more speed to be preferred over a slightly better latency (like in 3000-CL15 vs 3200-CL16) or are we talking about unnoticeable theoretical differences here?
-Is a 4x8Kit to be preferred over a 2x16 kit? Most builds use 2-module-kits...

What are you using your computer for ?
Obviously you need the amount of RAM to be able to use your softwares, regardless of speed.
The example you give ( (like in 3000-CL15 vs 3200-CL16) is really unnoticeable, especially with an Intel CPU which is less dependent of RAM speed than Ryzens.
If you are gaming, I'll pass and let other comment; I do mathematical modelling and do not game at all
