An i9 for a work PC? Seriously? What did they think you were going to do, compile massive amounts of code all day? Even my current CPU, an R5 4500, is probably overkill for basic office tasks (but it’s perfectly adequate for gaming on if you’re not interested in the latest AAA slop), and it’s truly a low-end part, but an i9 or R9 for basic office tasks is ridiculous.
The Goanna browsers will run on pretty low-spec hardware, and there’s also h.264ify for sites like YT, unless Google blocked YT from loading on Goanna browsers.
