My CPU is i5 8400, mainboard is Gigabyte Z370XP-SLI, VGA is MSI GTX 1080. Which RAM ( (2400, 2666, 2800 or 3000 MHz) I should invest in for best price/performance in gaming and daily office work. I also need this system to be futureproofed in at least 3 years. Thanks.

Does it mean 2666Mhz is the minimum I should go with? And what're the factors that I should check if choosing higher ones.

Thanks for the info. In case I upgrade the CPU to Intel i5 8600K, what's the optimal RAM speed I should go with?

P.S: just a side question if you don't mind... is it really worth to upgrade CPU to unlocked version :-? Thanks again.
