In case anyone else wanted to check, PS5 has[1]:
> Memory: 16 GB GDDR6 SDRAM
So unless the RAM price jumps to 4x the price of a PS5, getting a PS5 is not the most cost efficient way to get to 64 GB of RAM.
In comparison, PS3 has been used to build cheap clusters[2].
Yes, stupid comparison really. Also 64GB is pretty high-end from a consumer perspective. Most would do just fine with 32 as 2x16GB.
Maybe if they expect to upgrade within a few years it would be fine. But when I built my current computer 11 years ago I also didn't expect to need 16 gb of ram and only bought 8. 5 years later 16 gb of memory was a requirement for both software and games I was playing. And now 11 years later 16 gigs is not enough for fairly "simple" 3d modelling and 32 gigs is pretty close to the minimum requirement to fully utilize other modern hardware.
I bought a 16gb desktop for work in 2011, plenty for Visual Studio at the time. 8 is a bit skimpy for a desktop build even in 2014.
Speaking of 11 years old, I just put my 4790k out to pasture. It was a good CPU for a long time, but it got a little long in the tooth for modern workloads.
