Oh they won't be cheap, but right now a 5700G is only about £20 more than a 5600X which makes for an interesting choice. The 5600X is a better gaming CPU, but you can have two more cores and a GPU thrown in for £20.
The 5600G is down to £220, a price that would possibly get you a 3200G not long ago.
If you are building a kid's first gaming rig for minecraft etc then £220 for CPU and GPU in the current market seems pretty good. Compared to a couple of years ago when you could get an RX570 for £130 it sucks, but that isn't where we are these days
Edit: OTOH, currently the Ethereum price is crashing while the total network rate is going up causing the network difficulty to be an all time high. Given how energy prices are going in this country, fingers crossed eth mining on GPUs is about to die off at least here. It is supposed to be dying off in the summer anyway, not that you can believe the eth2.0 schedule.
