Just one more answer - why not? It seems to me that GPUs are heavily underutilized most of the time a PC is running. They kick in only in a few rare applications like gaming/rendering/video decoding and run at literal 0% utilization the other times (atleast according to what windows task manager tells me). On the other hand, the CPU is often busy. Particularly for a text editor, theres a good chance the user is running all sorts of CPU heavy stuff like code analysis tools, databases, compile loops etc.
