Not really. Non-gaming tasks are so diverse that it's really hard to capture performance in a video. Fortunately, if you understand the dimensions of performance you can make a reasonable guesstimate about how much an upgrade will benefit you.
Open the Performance tab in Task Manager and see where you're getting bottlenecked. Boot times and application loading are severely bottlenecked by the random I/O performance of a hard drive, which will be indicated by 100% utilisation of the main drive. For general responsiveness, it's overwhelmingly important to get a decent SSD. If you're running out of RAM, that's your bottleneck (bearing in mind that an SSD substantially mitigates the performance impact of running out of RAM).
The CPU graphs show utilisation on each core, which will indicate whether you're bottlenecked on a single core or all cores; looking up the single and multithreaded performance scores on cpubenchmark.net will give you a good idea of the performance difference between your current CPU and your prospective choice of CPU. For example, an i5-3570K scores 2028 single and 7172 multi, versus an i7-7700k's scores of 2583 and 12037, giving us a performance increase of 27% and 68% respectively.
