Upgrade Solutions for CPU/cooler/Mobo/PSU

Hello everyone,
I was inquiring about upgrading some parts and whether it would be worth it this time or if I should wait until the next round of CPUs come out.
My current build:
CPU: i7-8700k(slight overclock to 5ghz)
cooler: corsair h100i v2
Mobo: Asus prime z370-a
Ram: corsair vengeance ddr4 3000 4x8gb: 32 total gb
GPU: EVGA 3070 xc3 super
PSU: corsair 550 gold

I'm looking to possibly upgrade all parts besides the GPU and ram. At this point in time is it worth upgrading? Would I see any sort of performance increase gaming in 2k resolution by upgrading the CPU? What are my options if I'm looking to spend $800 for a CPU/mobo/cooler/psu.

Use your present cooler ... just get a LGA 1700 mounting bracket for it.

CPU: i7-8700k(slight overclock to 5ghz)
5 GHz on all cores is arguably more than a "slight" overclock in terms of multithreaded application performance. At stock, the 8700K can boost to 4.7 GHz for lightly threaded workloads operating on a single core, but as active cores increase, the boost clocks will drop until they are down to 4.3 GHz with all cores loaded. So, the overclock can potentially get you up to around 15% more performance in certain heavily multithreaded applications.

That likely doesn't make nearly as much of a difference in just about any current game running at 1440p with maxed settings on a 3070 though, as games will tend to be more limited by graphics performance. But that goes for the newer CPUs too. Core counts have increased at a given price level, but few current games will benefit much from having access to more than 12 threads. And performance-per-clock didn't really improve by any significant margin until the latest 12th-gen processors launched, and even then, the differences tend to be minimal in graphically-demanding games.

Compared to newer processors, an overclocked 8700K should be roughly in the stock 10600K / 11600K range, and just a little behind the new 12400. There are new 12th-gen i7s and i9s as well, with higher clocks and more threads than the 12400, but really any of these processors should tend to push average frame rates within several percent of one another in the majority of modern games. There may be less graphically-demanding esports titles and older games that would show more of a difference in frame rates, but those will probably be pushing more frames than your monitor can display anyway. So it doesn't really seem worth the upgrade yet, in my opinion, as I doubt you would see a visually-noticeable difference in frame rates moving to something like a 12700K, unless perhaps you are streaming or otherwise multitasking while gaming. Moving up from a 3070 to a 3080 would likely make a larger performance difference in most demanding titles, but you didn't do that, so spending even more for a smaller improvement might not be worthwhile either. I would probably wait another processor generation or two, by which point games might start to see more benefit from the newer hardware, and the processors will likely have improved a bit further too.
