The minimum system requirements for these software are pretty much demanding, which means you need to have a powerful enough system to work with them. Some of the most popular professional productivity software (video editing & others) include Adobe Premiere Pro, DaVinci Resolve, Final Cut Pro X, Adobe Premiere Elements, Corel VideoStudio Ultimate X10, CyberLink PowerDirector 17 Ultra, AVS Video Editor, Pinnacle Studio, Kdenlive, Blender, Autodesk Maya, AutoCAD, SketchUp, Revit, etc. Besides a powerful CPU and a decent graphics card, you also need a good amount of RAM for video editing. So, a GPU can help a bit, but video editing & rendering is largely dependent on the CPU, and the faster the CPU you have with more cores, the better performance you will get in video editing or productivity.

Also, good modern-day GPUs do come with efficient hardware-based encoders and can help in video encoding. However, some modern video editing software can take advantage of graphics cards through GPU acceleration (GPGPU) by offloading some of the work from the CPU.

This is because video editing & rendering are majorly CPU-intensive tasks and require a fast multicore CPU. If you are into professional video editing and video rendering then it is imperative that you need a powerful processor.
