hiya. so I was wondering if any of the hardware in my rig is causing bottlenecks in performance for the other hardwares?

here is my rig build:

some of my friends said my RAM speed might be causing bottlenecks...while others say maybe the motherboard? I have no idea...kinda difficult to compare all the different performance stats for each hardware, so I ask the tech-savvy members here. Any advice would be appreciated
