Question Is there a big difference between a 2666mhz and 3600mhz?

I know higher speed number is always better but I want to know how much of a noticeable difference is there between 2666mhz ram and 3600mhz ram on an i9 9900k and Gigabyte Z390 Aorus Ultra. I will be gaming and general productivity. FYI, the difference in price between the two "identical" sets I'm looking at getting is $150. One set is 18-18-18-43 1.20V while the other set is 18-22-22-42 1.35V. How much of a difference in performance speed would I be missing out in games and general productivity if I went with the cheaper set? Thank you for your help!

as it turns out the game took around 48GB and other stuff took ab 20GB making the system usage to around 70GB and more than 64G of physical memory was in usage so I figured I might as well get 128GB..

Still would like to know, what exact game is capable of doing that.

1. Oloy... no, just NO !!
2. New vs. used... concerned about performance & stability.... easy choice there IMHO !
3. Virtually ALL currently existing games are GPUlimited for the most part, and after that, somewhat CPU limited... Very, very few will have any issues with ram usage, unless of course you only have like 4 or 8GB....

Are you 100% certain that you are looking at "SYSTEM" memory (RAM) vs. "VIDEO " memory (VRAM) usage ?

update report so I got the used 2666 mixed set and overclocked it to 3067mhz at 16 18 18 38 stable

I tried out a set of owl oloy 3200 16 20 20 38 from newegg and it was unstable at advertised settings

I run skyrim with 170 mods (downsized on this run-through from over 260 mods), everything from weather to lighting to cities to hdt-smp, all 4k/8k mods, and barely use 13Gb of ram.

My daughter runs all kinds of mods in minecraft, and hasn't topped 10Gb of ram yet.

There isn't a modded game (and that includes ones like FarCry with HD texture pack) that use even close to 32Gb of ram.
