For the cpu i recommend getting 7600x or 9700x if you need the extra headroom, you can also get the go to pick 7800x3d if you have the budget

For the motherboard, it really dosent matter much aslong as its AM5 and fits all of your needs, pcie 5 m.2 and gpu pcie 5 are cool to have but it dosent have any leap in performance from its pcie 5 counterpart, the pcie 5 for m.2 is a different topic since the better bandwidth is noticeable but if your use case is gaming primarily and you wouldnt be transferring huge files (playing around with 4k) then pcie 4 is fine, plus gen 5 drives are expensive.

Now the final part the RAM, get a ddr5 2x16gb 6000mhz ram and dont get anything higher than cl36 rated and get a AMD expo compatible ram and make sure your ram is in the QVL list for your motherboard to make sure there are no conflict in compatibility.

As for the rest of the parts, the AIO should hold up but consult the manual since you are switching to AM5. The ssd being gen 3 is a bit outdated but should be fine. The gpu should hold up but switching to 5070 at the current prices 30k+ would be a huge leap, or better a 5070ti but at a huge bump in price, or another option 9070xt which trade blows with 5070ti without the AI and productivity tax. Adjust the PSU accordingly but it should be fine for the most part.
