And for maybe 700 or so you could do all new parts with a 12400 or a 5600, and a RX6600 or similar.

You can often get a 12100f/rx6600 PC built from new parts for right around $600 when the rx6600 goes on sale for $200 (US prices).

So yeah $700 is feasible with a better CPU or GPU. If I had $100 extra to spend tho I'd go 12100f with a 6650xt or 6700xt instead of a 12400f/rx6600 though.
