I will say only 1 thing.
I was able to run odyssey on 10yo rig, of course, it wasnt good experience on planets, but space worked perfectl
Now only things which I changed are:
slighty more ram
slighty less old GPU (but it still is 6yo GPU)
so, with:
10yo CPU
6yo GPU (btw, I bought it for...60$

)
16gb ram
I can run ody at 40/60fps on planets.
Tell me more about "I need expensive new rig to play, for thousands dollars".
Sure, I understand, that due to counting everything in dollars one countries are more expensive than other, but sorry, it isn't my issue. I'm only saying, that 6/10 years old rig can handle even ody. Sadly, it isnt my fault. Time flow, games and programms are more and more demanding, even the strongest rigs sooner or later will require some new parts.
