Your rig's fine honestly. Just pick up an RTX 3060 or something similar and you'll have far more GPU grunt than necessary for 1080p/60 in pretty much any game. Your ram is honestly fine, but you could go up to 32 gb at some point for an easy upgrade. Your CPU's fine and will remain fine for a long while yet. Are you on SSD? That's the most immediate "feeling" upgrade path you can take on PC, the whole system, including game applications, just immediately feels much snappier on an SSD, so if you're still on mechanical maybe consider upgrading to SSD. That's literally it, you've got a good machine there man.
