Not even sure it was that, it just didn't wow compared to the pretty bad competition.
It's the same price as a 4060 but only 10% faster, likely draws more power, less mature drivers, and probably doesn't have enough horsepower going forward for the 12Gb ram to matter.
It also requires rebar (which I'm not sure my son's computer has enabled, and it may still be running in pre UEFI mode so a bit of a faff to change and enable)
I also ruled out plenty of other cards before settling -
4060Ti was too much extra cash for only 20% more performance and no extra vram.
3060 12gb - slower than the 4060 in most sensible benchmarks and not much cheaper.
7600xt - has 16gb vram, but not enough performance to actually use it.
6650xt or 7600 - both slightly cheaper than 4060, but not cheap enough for the slightly lower performance.
