Depends on what you wanna use it for. If you wanna host a bunch of services, do scientific computing, or play modded video games with really bad memory leaks and memory optimization, perhaps?
The problem is memory is expensive because fabs have switched to making HBM3 and EEC LPDDRX5 (soldered memory, like what's in a phone and some laptops). So even when the crash happens, we won't get a mass sell-off of useful consumer hardware. Likewise, the "GPUs" don't even have video outputs.
