I have an i7 4770k clocked at 4.0 Ghz,16 gig ddr3 ram,3 different SSD,with an ASRock Z87 Extreme4 mobo,and currently a Asus RoG Strix RX 580 8 gig OC gpu,I'm not going to have the funds like I thought to get new CPU,Mobo,Ram,and GPU like I thought,so I need to know what is the most powerfull GPU to buy without bottlenecking the crap out of the system
Your current GPU is about the best I would go with without bottlenecking the CPU too much. If you were to go higher to like a GTX 1070, it would not be a good balance, as the CPU would become too large of a bottleneck.
well,this system was given to me by my Manager after he built a new one 2 years ago,and all I had to buy was a GPU and operating system,and he was running a 1080ti in it with no issues
Any currently sold GPU with similar or more video memory would bottleneck quite hard so you wouldn't get the full usage out of it. The 4770K is coming up on being out for 10 years so while it might not seem like it, it's quite outdated to be used with a newer video card.

For example with a RTX 3070 -
thank you for that link..says a 2060 will give no bottlenecking,and an RX 6600xt will only give 2.3% bottleneck that says to not even worry about
but at the same time it says a 3070ti isnt powerfull enough for a Ryzen 5 5600x?
That's not the results I am getting based on your original post stating you have a 4770K.
Simply, processor bottleneck is bad because utilization of your processor will be on maximum and it will throttle other programs that are ran in background. Also you won't experience maximal performances that your graphic card offers.
4th gen i7 had been the god of 1080p gaming many years since intel improves ipc very little from 4th to 7th gen, they only started to do it when the ryzen came out and give intel pressure. If it's me I wouldn't worry about bottle neck too much, anything under a 3070 should be fine. If you are playing in qhd or uhd then this question doesn't exist in first place, any gpu on market is fine unless you are playing some simulator games that has crazy cpu demands.
