In the past it was always difficult to gauge how fast a new computer ran.
Most people use their computers for email, browsing the web and maybe doing their home finances.
Not a lot of load for a modern day computer. We used to give new computers a workout by popping open a large PhotoShop file to see how fast the processor could apply a filter. Or load Word and scroll through a long document and count the seconds it took to get to the bottom of the file. But those gauges of performance can all be thrown to the wind. Now there is only one way to determine just how fast a computer cooks.
