At least buy a custom built one from someone who knows what they’re doing. The difference between a $800 built computer and a $800 pre assembled computer is night and day 

https://www.reddit.com/r/buildapc/ There are a lot of helpful people there, i'd suggest looking into building the pc yourself! You can get way better pc with that money if you build it, they'll help you out if you make a post there! :) GL

Trying to get a decent desktop in the 800$ range tomorrow at beat buy. Anyone have some suggestions I should look at when I go? Also Not really trying to build a computer because I really don’t know much about what’s good and what’s not ect

Desktop in 800$ range?
