I would choose a 5700x instead of the 3800x, it's better and if you are comfortable with AliExpress it's 60% of the price, (just get an high review high amount of sales offer and you're good) and it consumes less so the stock cooler is kinda enough, but maybe it's better to get an am5 motherboard and get a 7500f, which is very similar in price and performance to the 5700x (faster but less cores, depends on what you need but roughly the same in games), only thing you have to get a b650 and ddr5 ram which can be a little more expensive.

as for the GPU, the 3060 is a little too weak for a 1000$+ build, in that price range (considering usually the gpu takes around 40-50% of the budget) so if you are willing to spend a little less on the motherboard (180$ for an am4 motherboard is quite too much, i would spend a maximum of 80$ for a b550) you could get a 450$ gpu, idk the gpu prices in your country but for that price usually one can get a rx7800xt or an rtx4070 for \~500$, which suit a 1000$ build much better as they can run anything in 1440p.

below 450-500$ anything from nvidia below the 4070 isn't great for the future (i own a weaker gpu as my build is less expensive all around but that's my opinion tho) unless you buy used parts, so something like an 3080 or 2080 ti, so i'd rather look into amd only if you want to spend around 300$, so something like a 6700xt, used 6800 or 7600xt(xt only).

i know nothing about sound cards so idk if you actually need it, or if 160$ is too much.

case, ram, psu and storage are good
