CPU upgrade for my old rig (Intel)

Once you finally get your hands on a laser projector, feel free to reach out about what you intend to do with that outdated junk you claim to own.
It’s much like this situation here, which clearly isn't the case. And a laptop that struggles to run Photoshop? Please...
The solution was already laid out for you: more RAM and increased storage capacity for both working files and long-term data.

If you’re feeling particularly lazy about dealing with a BIOS update—and honestly, I can't say I blame you, because they can be such a headache—just go out and hunt down a used Core i5-8400. You should be able to find one on eBay or at a local tech shop for under $130, maybe even dipping below the $100 mark if you're lucky. It'll be more than enough power for basic office tasks and some light photo or video editing, and the best part is that it'll definitely work right out of the box without forcing you to mess with your BIOS settings.
