no clue on the A12, it's pretty much obsolete but I'd say 50 - 75% on the i3, starting on the high end. it's a good CPU...but I don't think it's really outclassed by the i3-9300 much.
the GPU's I'd say 80 - 90% of current value, probably between the two or on the lower side since used. but, no taxes and a bit in savings is a win win. though you may have to fight BF pricing if you put them up now.
For me personally, I'm waiting to hear more details about the Cyberpunk PC performance before I upgrade my gfx card. My gut says that I will buy a pre-owned RTX 2xxx, based on the fact that CDPR showcased their latest demo with a NVIDIA card.
If you can wait a couple months - your card will be in super high demand when the official specs are released prior to the launch date.
