A little work and $550, yeah. Without all the current-gen goodies like PCI-E 4.0. And zero resell value when the system itself becomes legacy.That's why I won't upgrade to a 3000 series Ryzen. Going from a 2700x to e.g. a 5900x is a different story. We are talking about a very noticeable performance uplift in any scenario at the same power consumption.
Gaming at 1080p is +47%, probably a bit less @ 1440p but still noticeable. And all this with little work.
