I would have gone AMD in the first place if this happened at the time of my purchase.
Well, you’ve got better judgement than me. l’d been running just Intel for ~25 years and was comfortable with them, and even when ordering the replacement, still wasn’t absolutely certain that the CPU was at fault until the replacement (temporarily, for a few months) resolved all the problems.
Moving forward, I expect I’ll use AMD unless they manage to do something like this.
My last gaming PC served me well for almost 10 years before I did an in socket upgrade.
Yeah, not a lot of annual single-threaded performance improvements since the early 2000s. Can very easily use older CPUs just fine for a long time these days, depending upon workload.
