I've been postponing upgrading my PC for so long, and when I'm about to pull the trigger, DDR5 comes out of the closet looking damn interesting. As far as I remember though, we had to wait a few months before DDR4 started to outperform DDR3 back when it first came out, so... meh?
It's funny how 4800MHz at 1.1v sounds really nice at the moment, but in 10 years it's going to sound as outdated DDR3 does right now.
