Console convert here, I'm struggling to understand the importance of having 32gb of DDR5 ram specifically. I got the 7500X3D microcenter bundle for $300 and paired it with an RX 6800 XT I scooped for $280 second hand. The bundle came with a single 16gb stick of gskill ddr5 c36 6000. The plan was to use it for a bit on bazzite to see how the OS manages, then I'd see if I wanted buy another one later, at hopefully a lower price (doubtful). I think I'm good, or maybe I just don't know enough..

3 things:

1) 32gb for gaming

I usually target 4K 60fps, which my setup seemingly handles well. Gameplay is stable, no hard drops below 45 that I've felt or seen. I have to turn on FSR and set it to Quality for something like Expedition 33 (low settings), or RE9 (max settings, RT on high). 1440p is a non-issue, but truth be told I havent spent much time at 1440p, everything I tested ran butter smooth with settings cranked up. With 32gb, Can I crank up settings at 4K? Do I get more FPS? How would more affect a game really?

2) 32gb for 4K 60 game capture

I also make youtube videos, but unless more ram reduces 4K rendering times, idc tbh. I would like to record 4K 60fps gameplay though. Linux has lightweight recordering software, but I'm worried 32gb is still not enough for recording a stress test or longplay of a demanding game. I'm also not sure how ram affects game recording in general. My assumption is that recording quality is tied to the GPU, which has its own vram, where does system ram play into this? Should I just get an elgato instead of software based recording?

3) 16gb ddr5 for $100, secondhand

I found a listing for the same brand stick second hand, its $100. Should I wait for ram pricing to go down in general? Or is $100 a decent price all things considered?

Please advise.
