That was true when most software was desktop software. Most software now are Web Apps so the local speed of the development computer means less. 30 years ago there was a big difference between the performance of a current computer and a 3 year old computer. These days there isn't a huge difference and a well maintained older computer can still perform well as compared to a current computer.
