Hello I am wondering what gaming pc I should buy I don't want it to be too expensive, I want to be able to play a few games but also using photo shop and rendering videos.
Need much more details here, what is "too expensive" exactly? What country are you from, what games are you playing? Do you need parts or a pre-built?
A good pre-built system with parts that will last start at about $1,000.
Honestly, I would avoid a pre-build if at all possible. Too expensive for what you get.
Building is the way forward (cheaper and you can build what YOU want.) It has been compared to "lego for adults" so don't worry, anyone can do it. There's even YT videos that take you through the entire process.
What is your budget and what sort of games are you wanting to play?
