Hi Chris!
 
I was in the same boat as you as of yesterday. I picked up a 13900k & 4090. I came home and watched reviews before setting it up, and decided to take everything back & wait until next year for Meteor Lake. 
It was the power consumption, heat, & LGA 1700 being EOL that finalized my decision.
I have a similar setup as you but with a 10900k.
You have an awesome setup now. What is your main use? If it's for work absolutely upgrade now, but if it's for gaming can you wait until later this year for AMD's X3d cpu and see how that looks? The other is Intel's 14th gen which will be on a new chipset (LGA 1800).
 
 
 
 
 

If you are just going to be gaming don't bother with a 9 series of either brand they aren't worth it just for games. Get the 7 series of either one. Both are honestly great and will serve you for years to come. If you're the type of person that only does a system overhaul once every few years it honestly doesn't matter which way you choose. The future upgradeability of AM5 will be lost on you if you don't plan on doing in socket upgrades and the current LGA1700 from Intel going EoL will not affect you either since by the time you do upgrade you'll just have to upgrade the entire platform anyway. 
 
Taking all that into consideration I'd honestly say go with an Intel i7 13700K. You get 8 more cores than what is currently offered on AMD's 7 series equivalent and you have the option of carrying forward your DDR4 if you don't wanna splash out for DDR5. Regardless of RAM though even with DDR5 in the equation I'd still say you get more bang for your buck on an Intel platform. Z690 boards can be had for much cheaper than AM5 and they all pretty much have feature parity in PCIe gen 5, numerous NVMe slots, plenty of IO....etc. 
 
As for temps, be warned they both run much hotter than you may be used to. My Ryzen 7 7700X pretty much stays at about 90-94C even with a NZXT Kraken X63 280mm AIO on it. The Intel i7 13700K I just got in, does run a few degrees cooler at 85-90C on a similar AIO but they are both hotter than anything the previous generations ran at. The Intel chip does seem to respond better to overclocking netting me a pretty easy 5.6Ghz P-Core clock while the Ryzen 7 7700X can only manage about 5.5Ghz. Though they both run an out of the box all core boost clock of 5+Ghz this generation.

What method of applying thermal paste did you use for your 7700X? I've heard these chips are best with a pea sized dot in the middle?
