looking to get ram for my new 10400 pc, the 2666 is $10 cheaper. Would it be better to get the 2666 or 3200?

My 10400f will be on a z490. I got a buddy who overclocked his 2666 to cl12, if the 2666 is better than I would get the same one as him.

It's not a 100% accurate calculation, as different tasks will benefit more from speed than it will 'latency' (to a point).

I think the calc is (CL / speed) x 2000 = nanoseconds (and lower is 'better').

So (12/2666)x2000 = 9
Vs
(16/3200)x2000 = 10

So the 2666 @ CL12 would be ever so slight 'faster' - but you're not going to notice that in real-world uses, and in some tasks, you might benefit from the higher speed.

Fast ram is primarily of benefit with integrated graphics; a moot point here with a 10400f.
One metric is to divide the speed by the latency. The higher the better.
Still, excepting special cases, ram is not very important to intel processors when measuring production or fps. The memory controller is very good at predicting what ram will be needed and having it ready in advance.
The first rule is to get enough. Whatever that means to you.
