I decided to stick with the stock cooler for now, if I need to upgrade later then I will. I was going to downgrade the CPU to the 5600 as recommended to save some money, but the prime day sale kicked in and the X ended up being cheaper. I also switched to the 980 Pro rather than the Evo 970, once again courtesy of our capitalist overlord's Bezos day. I managed to snag a new RX 6700 XT for $310 on Amazon a few days ago, but it's shipping from Portugal so we'll see if that sticks.
Really appreciate all the advice, yall made it a lot less intimidating.
Honestly, I think you did a pretty good job overall with managing cost/parts.
Do agree with the others saying the 5600 is a better buy than thr 5600X (the difference is stock boost clocks, and X moniker cpus also have XFR boost, whoch bumps clocks by 100Mhz, neither are really worth the cost difference between the models)
My only advice would be that your CPU isn't going to be running high enough to really require a tower cooler. The stock wraith that comes with the processor should be good enough if you want to save the 40 bucks.
Other than that good job picking things out on a budget!
The 5800x3d cpu is under $280 on Amazon today. Well worth it if you're going am4 to just go ahead and buy once and cry once to max out your utility of the platform. It's a great CPU. Really shines on poorly cpu optimized games like almost anything made in unity.
