because if you use up all your ram the rest goes into your hard drive
which is infinitely slower
if you run one instance of a game you wont notice
but if you run a modern game
and have some music in the background
and another window with 4 keks
and youre doing other shit like torrenting etc etc

then half your shit lives on the hard drive, and your ram effectively works at the speeds of an sdd/nvme
which is multiple order of magnitude slower ***in latency
but also in raw throughput

just buy the fuking ram already
you will notice 100 bucks in ram more than you will notice 100 bucks in a keyboard
and op spends 300 on kb+mouse
its irational to go with less than 64 gig in tyotl 2025 when your budget is 3.7k
