switching platforms is a very expensive move these days.
It’s just a motherboard and a cpu. Everything else is cross compatible, likely even your cpu cooler. If you just buy another intel chip… it’s just gonna oxidize again.
Personally i’d wait for the next release to drop in a month… or until your system crashes aren’t bearable / it’s worth making the change. I just don’t see the cost as prohibitive, it’s about on par with all the alternatives. Plus you could sell your old motherboard for something.
