Very good ram
I had g.skill trident z at 3200mhz before. Not disappointed and still going strong. These low profiles don't take up much space (thank you, given the thickness of modern ventirades).
32 GB is becoming useful in today's gaming world, where you need slightly more than 16 GB (if only Windows took up less of it, like Linux...).
I've got 31.8 GB of ram available and I'm using around 17 GB playing my current game. I think I'll be fine for a while.
