I myself have come to this section for a build, only to be left with more questions.
I would HIGHLY suggest, ESPECIALLY as a first time builder, to watch some videos and compare builds and think of TRULY what you need.
Although there is a sticky not many read/understand why/what the requirements are.
I love a game called Rust, put together a sick PC a few years ago with a 5950x/3080/128GB ram (literally the best you could get at the time) thinking I would get better performance than anyone else - I did not.
Rust is heavily dependent on L2cache, I didn't need more cores/threads - they needed better performance on each. My GPU and RAM had little to do with what bottleneck that I created.
I spent ~$6k on that build - a few later I put together a 7800x3D/4070/64GB for less than half the cost and it increased performance 500%.
The number 1, 2, 3 through 20 suggestions I have for you is to learn the significance of each part and go from there.
Do you want to buy a pre-built for $3k that you could build for $1.5k and then ask us everytime you have an issue? Or would you prefer to spend a week or two to learn the mechanics, buy that 3k build for 1.5k and make improvements based on your needs?
