TL;DR: I'm thinking about asking for a desktop computer for Christmas and I kinda need some advice

For the past 5-6 years, the practicality of a laptop has been worth the drawbacks. Now, as I start to do things which require more power from a computer, it seems to be becoming a bottleneck rather than freeing.

I know very little about things like motherboards, power supplies, anything AMD, and desktops in general so I figure it's not worth building one from scratch for me

What's a good desktop? I'm looking to get something better than my laptop (16 gb RAM, i7-12700…k?, laptop RTX 3060, 1 TB SSD) and I have a lot of money saved from never participating in capitalism (I don't want to spend a butt load of $$$ on this though).

Does anyone have any advice? Should I get a prebuilt? Assemble it myself? Try AMD parts (not sure about this though)?

Just trying here before I dive into… Reddit
