Bimbam You want your workflow to be as fast as possible and whatever you can justify paying for will make that process faster.
If you spend 100x the time thinking about what to code than you do running the development tools, as I do, a fast computer doesn't necessarily make the process significantly faster. But when I got a new computer a few years ago, which I seem to do only about every ten years, I bought more power than I really needed (an Intel i9-9900K 3.6GHz CPU with 8 cores / 16 threads, 32GB RAM, two 500GB SSD hard drives) so it wouldn't become obsolete too quickly.
