Looking for advice on GPU choice for my son's PC, despite prices being kinda crazy rn...

Have been holding off on an upgrade for quite a while (currently running a vega 56), however he's just bought the latest Forza and found it won't run on vega architecture at all, as his birthday is coming up decided I'd get him an upgrade.

I'm avoiding any 8gb cards so in the price range I've got the 9060xt at about £400, the 7700xt at \~£440 and the 5060ti at \~£460. Unfortunately the 7800xt is out at £530.

Any advice appreciated 👍
