one last thing, if you do buy an 13th or 14th generation intel, please ask someone to update the bios for you. It is to prevent the cpu from getting too high voltages. It bakes the CPU to medium rare. This was the reason I went for a laptop with AMD ryzen series 7.
Above is also the reason you should run a heavy benchmark to stress the CPU and GPU. If there is anything, it will show under stress, just like humans. ^^
