Many parameters need to be set to answer the OP question.
Budget. Requirements. Etcs.
I got my 9800x3d a few weeks ago, it's a bit faster than my 7800x3d, but it's not shockingly faster, so if you don't want to wait weeks or potentially months for 9800 going 7800 isn't a bad option still, plus you can just pop the CPU out and put in a new 9800 later as they use the same board and socket type.
IF price/$ is an issue, IMO despite all the crap talking on Intel, the 14600KF chip is a great performer for the discount $ you can get it for now, and it overclocks really well with a decent AIO cooler. The motherboards are cheap for these too, you can get a really good one with 3 or 4 SSD slots for a couple hundred bucks now.
Big thing is the GPU, the new 50 series RTX cards are coming in just a few weeks, jury is still out on reviews for now, but it looks like the 5070/ti series should be a good bang/$. Depending on the market, there may be some good deals on the previous 40 gen series of GPUs in both the new and used market if having the latest and greatest isn't important to you.
Of course what games/stuff the PC will be used for primarily is a major factor to consider. AH is not very demanding, but if you play DCS or some of the AAA titles out there, and/or use virtually reality, getting a 5080/90 and a fast CPU is going to be a better experience IMO.
CPU/GPU are always the 2 most important components, it's like range/wind for long range shooting, by far the 2 most critical thigs to ensure are right for what you want to do. Once you figure that out, it's just a matter of picking the supporting components, and there are a ton of "right" selections in each category these days.
