No, in 6 years DDR5 will be the DDR4 right now, and DDR4 the DDR3, and DDR3 the DDR2. See what I'm saying?
And yes, it won't give you much of a performance gain right now than a DDR3, because there aren't as demanding games/programs yet. In the future though, there will be. Just like the past vs now. How games used to be MBs, now they're gigabytes. Then they'll probably be terabytes in 20 years.
Plus, what's the point of USB 3.1? USB 2.0 is fast enough, lmao
