Just about every factor

The cpu (i5 13600k) has more cores which help in many games with rendering, its also faster so the gaming performance will be better than with the ryzen 7 5800x

The cooler is better because its one of the best air coolers out there and its pretty huge, it keeps the cpu cool

The motherboard is newer and its ddr5 (ddr5 is the newest gen of ram) which puts it above the x570 you chose earlier

Ram is better because the speeds are miles faster and the timings (i cant rlly explain them so can someome else please) are better

The graphics card (7900xt) curb stomps the 3060 im every factor, its the difference of playing a game on 1080p high to 4k high,

The storage ( you could get an extra 1tb if you want) is way faster than the original build so itll load stuff quicker

The case is way bigger and has better airflow to cool your system better

The power supply is a lot more trustworthy and has 350 extra watts which will come in handy

And the case fans are by corsair and their generally very good

Yeah so thats the things i can list off the top of.my head

You’re the man. You have no idea how much I appreciate it.

Won’t I need an OS? And possibly wired/wireless capabilities?
