For the next gen of gaming, I'd go 16GB, prebuilt computers are skimpy with DRAM and they now average 6-8GB, if looking ahead for any longevity beyond maybe 6-9 months the 16 is the way to go. DRAM use increases in gaaming and apps every 2-3 years and back 2010 or so most were saying 4GB is more than you'll ever use, then it went to 8GB and that's been the standard entry level for a couple years now
