Its quite hard to tell how long any component would last, it depends on a few stuff, Intel is fairly well known for their processors, but AMD is not far behind in low to medium end CPU's. It depends on how hot the CPU will run, in what condition it is and etc, but from personal experiance the best CPU's are made by Intel, theoreticly Intel should laat longer, because AMD processors are power hungry and therfore runs hotter, but even that wont make a big diffirence. If you want to play Games Intel will be your choice, but for work, video editing, redering and etc AMD will do the job. Good luck with the descision and happy holidays.
