I have a dell inspiron 5676, came with 2x4gb ram. I was going to upgrade to 16gb but do I need to, for gaming only? I played through shadow of mordor/war, and doing witcher 3 now and none of them seemed to use much ram. I will do divinity original sin 2 soon. I have been out of the loop on gaming for a while. Do any modern games really need more than 8gb ram?
