CAS - Does it matter THAT much?

Basically, the title. When looking at RAM and the CAS, does 14 vs 15 vs 16 really matter THAT much?  Will it be that noticeable? 

 

I ask because it seems like, when you look for 14 or 15 CAS 3200mhz RAM, you are looking at HUGE price increases, which makes sense, but does it really make sense in the grand scheme of things?

If you're not doing enthusiast stuff, even 16 or 17 is just fine. Is this for gaming? 

On top of that, cas 15 at 2400 will actually have worse latency than at 3200, because the cas number associated with ram is a multiplier.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Draws 400 watts under max load, for reference.

 

How many watts do I need? ATX 3.0 & PCIe 5.0 spec, PSU misconceptions, protections explained, group reg is bad

You can play with the numbers here https://notkyon.moe/ram-latency.htm Makes little to no difference in gaming, some difference in workstation tasks varies depending on program

Gaming and streaming. I will also do some video editing in the future as I work on my YouTube.

 

I am only concerned with 3200+ mhz, as I don't want to go lower than that.
