Dual channel vs single channel

[Renan003]

Hey everyone, what's up?
I came with two options for RAM on my new PC build:
This

And this

The only difference between those is that one is single channel and the other is dual, and the CL from the first one is 16, while the other is 17. Which difference is more significant? Dual vs Single channel or 1 CL? Or should I just go with the cheaper? I've tried to find this answer for myself, but the results were inconclusive.
Thanks for the attention!

the lower the CL the better the performance, Also, Dual Channel offers slightly better performance and system stability.

I'd expect the drop to single channel is worse than a single CL level. It depends what you do with your PC a bit though, for gaming you might notice a bit of difference but for general use you will not.
