Yeah I never understood people who work with computers all day economizing on their computers. Even from scalpers you’ll pay ~$6500 for top of the line parts and peripherals, which is about the cost of a high school student’s violin.
At one of my first jobs, when my boss got annoyed by some software being slow, je always said that developers should get the fastest hardware available, but as soon as they start testing or using their own software, the machine needs to magically turn into a 386 with your home directory on an NFS share. Granted, that was 20 years ago so 386 didn't sound as hilarious as it does now, but it was still a little extreme. But that idea stuck with me, and to this day I do test software on slow machines every now and then, looking for obvious performance left on the table.
1. In many countries $6500 is enough to start a business. I'd rather do that than pay for an overpriced piece of aluminum with a piece of fruit etched on one of the sides. What if I'm not the business type? That's fine. It's still probably better to save that money.
2. Modern computing is turning into a dumpster fire. It will be pretty soon that the Intel platform will work in the same way as the above-mentioned fruitty platform and you won't be able to run whatever software you want on it. While I agree OP is probably making his life extra miserable [1], I admire people like him, since their efforts will give us the next free/fun computing platform.
[1] I too run a Raspberry Pi at home, but I've long given up on turning it into a desktop machine. There is an easier way to run modern software on cheap hardware with a fraction of the hassle.
