Monero Mining

Selling my 3950x rig, considering finally building a hobby farm. In the past microcenter had great deals on ryzen 3600/mobo combos and am4 mobos for 3900x's were cheap, but now the bundles are replaced with less efficient 5600x's and am4 mobos are more expensive than the past. Are 3900x rigs still the value king? are the newer budget intel cpus any good? Curious to hear what people think.
