Recommended ram for gaming

Solution
If you do only gaming, 8gb will be perfectly alright.
If you game and stream videos or browse wikis at the same time on chrome, you'll need 12-16gb of memory
Just close chrome and other random programs and you'll be fine...
8 GB will get you through another year or so, 12 GB will be slightly future-proof and will last you about 3-4 years, as for 16 GB, that's more than enough to be future-proof till a long time (maybe 10 years, can't calculate how demanding games will get though 😛)

12 and 16 would be good. I had 8GB RAM and FF15 was using 7500-7800 of the 8000 available RAM. Added 8 more Gigs and RAM usage went to 8300/16000. So i would assume newer game would use more than 8GB RAM now.
