Question GPU/CPU-bottlenecks, upgrade or not?

[Meitran]

Hi everyone!
I mainly use my computer for gaming and are thinking about purchasing some new hardware. I normally play with a resolution of 3840 x 2160 as i use a ultra-wide. Currently i have I7 7700k CPU that is overclocked to 4,9 GHz and a GTX 1080TI GPU, 32 gb of ram and all ssd/m2 disks. Originally the plan was to buy the new RTX 3080 or 3080TI (depending on price), and just keep the CPU for now. But then i started to read about bottlenecking and how newer games support multicore CPU's. This leaves me with three options. I can either just keep the CPU if the bottleneck wont be too bad, i can buy a Intel 10700k, or i can wait for the next gen AMD Ryzen that is expected to be released soon (?)

So to the question that i am hoping you can help me with:
How bad do you think the bottleneck will be when playing at 3840 x 2160 and max settings in games, if i keep the 7700K?
Would a CPU-upgrade be worth it when it comes to performance gains?
If i do choose to upgrade, should i go for Ryzen or Intel?

My English is not the best, but i hope i managed to express myself

At higher resolutions you are less likely to bottleneck as your FPS is low due to gpu limitations. Running your very high resolution I would think any bottleneck would be small and only in a few games but there may not even be one. If me I’d get the new gpu and see how it goes.

If you were playing at 4K, odds are your frame rate would still be quite good compared to even the fastest CPUs as most of the load is shifted to GPU, barring any outrageous advances this coming generation of GPUs.

Thanks for the replies
Still not sure if i should upgrade my 7700k to a zen 3 when it launches (in october maybe?). Will it be any point in doing it when i only use the computer for gaming? How much will only having 4 cores slow me down, compared to having 8 cores? Still planning on combining this with the RTX 3080 and play on a 1440p ultrawide. I don't really care about performance testing, just about the real gaming performance.
