In this day in age, and if you're an average user, I'd be surprised if you didn't max out more often with 8 gigs of ram, compared to those with 16 gigs of ram. That's not to say it can't be done.
I'm running 32 gigs right now. I'm currently using 9.8 gigs. I have 2 or of 3 Edge browsers in use, 5 tabs in total. 2 Youtube videos are paused, and the rest are low end resource tabs. Steam on standby, Discord open, and Spotify open and ready. Closing Steam dropped it down to 9.1 gigs of ram in use.
Holy moly! This website is amazing. I wish it wasn't hamstrung by Internet Archive's rate limiting, though.
"The Internet Archive is rate limiting and then blocking this site due to increased usage. I have reached out to them. I also need to make some changes with this service to avoid hammering their API. Please check back after I've been able to get this fixed. "
