It's worth looking at an interim upgrade, as would cost very little to move to a 6 core/12 thread cpu, due to offers at the minute.
You could reuse your existing ram, and as long as you have an AM4 bracket for your cooler you would be good to go.
My basket at Overclockers UK:
Just ordered this. If the CPu is the only thing holding me back for the next few years then a £200 punt is worth it.
can't find the AM4 bracket for my AIO cooler so will procure another new one
