I’d say it depends if you can find the right person and what CD it is.
I got this for about $15 with shipping included from someone downsizing their TMBG collection - I’ve been seeking out a few singles/EPs from this band that never made it to streaming due to a label breakup and cancelled rarities compilation back in the 90s, so my CD collecting has been very specific. My CD collection is thus very limited.
From what I can see, a typical non-mint used CD runs $5-10 for more common albums. CDs actually do tend to still be produced for a lot of new albums (or at least what I listen to), though if I have to purchase an album, I usually go for digital download from artist website or their BandCamp.
For me, besides the hard-to-find tracks (besides through YouTube compression), the desire to keep it in good condition is less for resale value and more because I appreciate it as an art form.
But if you do downsize your collection and have two oddly specific CDs…
Anyhow, I don’t totally know about 8 tracks, but who knows - someone out there could want it. The band who made my CD actually did a limited run of their 2021 album on 8-track as well as a cassette run.
Actually, with the work done on box86/box64, you might be able to get stuff running well - last I heard, they got triple A games running around 45 FPS on Asahi on Apple M1.
However, it would be totally unsupported, and who knows how well the Apple M series optimizations will work on another member of the ARM family. (Although, I wouldn’t be surprised if it’s been tried on Ampere at least once.)
Really, the biggest issue is probably power usage - I don’t know if it’s enough to increase your power bill significantly, but it would definitely consume more power than say, an i7. This is due to Altra CPUs really being more for server usage - performance per watt will likely be better overall for those kinds of workloads, but you’re probably not going to make full use of the hardware. These systems are really more of server dev kits than daily drivers.
For a desktop, I’d just recommend a PC with a high end consumer grade CPU like an i7 or Ryzen 7.
