What mac should i buy?

So i am finally making the switch from a PC to mac. i couldn’t justify spending a lot of money when my computer was working fine, but now my pc has a crazy virus i can’t get rid of. I don’t have a lot of money to spend, id like to spend no more than 1500. i want something with a decent size screen, lots of memory, and fast when i’m on the internet. i mostly word process (i’m a student) and do photo editing.

ideas???
