I'm still gaming on 16GB I don't think there are many games that actually suffer from 8GB if you don't run much in the background.I've always personally doubled my required ram. If they recommend 8 I do 16. If they recommend 16 I go 32. To double it again to 64 just wasn't in the pocket book but from everything I've read about my needs 32 is the sweet spot for now. I was gaming on 16gb 8 years ago and I never had any issues. Personally, I'd never go lower.
