Definitely worth replacing for the performance at this point but is it possible it just needs a repaste? Thermal paste would’ve definitely dried out over 10 years and cause overheating symptoms.
I'm running one daily for the past ~12-13 years and the stability is impeccable but the performance is as you'd imagine. More likely that the motherboard age and degradation of various components would lead to instability, than the CPU itself.
