The more RAM the better, because the more memory you have available, the faster your PC can read data from hard drive storage.
For example, if you were to play a video game with 32GB of RAM and 1TB HDD usage would be at 5%, but if you had only 2GB of RAM then this usage would increase to 50%. If all games use up that same amount of usage monitor look at how worst it’s going to be. And it’s even worse when someone wants to work on something other than a game for once in his/her life!
