You're intentionally missing a bit of context here surely?
The OP (or his son) upgraded from a 4060 to a 5060, and is apparently seeing massive gains due to (what is likely) MFG, which is more often than not a bit poo, while paying more for a B-Grade item with a limited six months warranty than he would have for a very similarly performing 9060XT brand new.
To add, I don't believe
@Armageus even mentioned the combined prices adding up to a 5070ti/9070XT unless I missed something? I absolutely did, I stand by the statement and I was absolutely correct, the total expenditure would have bought a 9070XT.
Furthermore, there haven't been major stock issues for releases for a couple of years now, and there's been a healthy amount of either MSRP or close to options on launch day for most launches, prices do tend to rise after initial stock clears but the last time we saw a major launch it took a few days before the lower priced stock ran out.
