I've been shopping around for a single 8GB DDR4 RAM stick and I thought it would be simple like flashdrives, just pick the size you want, find a low price, and boom, you're all set. Well, I guess it's not that simple. I found a few other articles with people saying that it's literally just you paying more for appearance and brand recognition but is there a reason I should be buying a $60 RAM stick as opposed to a $30 one? Especially if I'm going to be using my computer for gaming? I heard latency plays a role, most of the ones I've been able to find are 13-15. As for speed, 2133 seems to be the standard but I see some of them going up to 3000. Does it really matter in the long run or am I sinking money into something so I can feel good about my marginal improvement?
