it doesn't seem right to pay more for a higher clock speed when you only need it for gaming. Fewer cores can actually be better if they're efficient. Since you're saving money and don't have a job, it makes sense to upgrade just the clock speed. The other system is in your garage and stays cooler, so you're right to focus on what matters. Go with the link you mentioned if it fits your needs.
For Ryzen you need two RAM sticks to get the best performance. The 9100F can only reach up to 4.2ghz on one core, so it won’t be much better than that. It’s usually smarter to focus on extra cores or upgrade to a more affordable older Ryzen CPU first, then add the Ryzen 4000 later. You might also consider the R5 1600 AF, which just came out recently.
