Question Used Laptop CPUs upgrade question

[MrJapan21]

Hy there,

I have a Sony Vaio Pro 13 i5-4200U.
I want to buy a used laptop that is good enough for RAW Photo Editing like Photoshop. The problem is there are so many cpus out there and Im a little lost. Im also looking for some 13 inch size display, not bigger if possible, and a good display for photos. Any ideas or directions?
Thank you

There are many hundreds of laptops you can pick from, would help if you at least narrowed the list by how much you can spend. There are not many small laptops with fast CPUs, they tend to be high end models that will cost more, like the Dell XPS range. Did you look on eBay and craigslist already sorted by price?
