Currently deciding how much I need to spend on RAM and I'm a little lost. I need to upgrade from 32gb to 64gb because I'm maxing out RAM with games/chrome tabs/Lightroom etc open. The rest of my system consists of a 9900k and 3080. What kind of speeds should I go for? I'm told CAS 16 is pretty standard, but I'm looking at G Skill Trident Z and I'm confused if I should spend $468 on 64gb CAS 16 (16-16-16-36) or $360 on CAS 16 (16-19-19-39).
