Updated hardware — no performance gains — fed up

What were you looking for in addition to significantly improved render times?  (10 minutes to 6 minutes is pretty impressive.)

Short answer, Premiere pro is antiquated, it just doesn't know how to use your hardware at full potential and probably never will, there is no serious competition and it will never get updated to use newer hardware properly.

People are lazy and most of them got used to premiere, there are alternatives like Davinci Resolve but the learning curve scares most users and they stick with Premiere, this means there is no point in throwing money if it sells.

At some point someone will say to you the MEDIA IS VERY IMPORTANT, h264 is very intensive on the computer and that's why even 28 cores won't do it, Nvidia 2080 ti it's not enough, 64gb ram is minimum for 4k and all that crap.

Well, it's not true, it's just premiere pro's fault, you can cut  A7 III files perfectly fine on a tablet like apple's ipad pro, or davinci resolve with no need for transcoding.

If don't want to learn another NLE then suck it up.

I am not someone that works for premiere, but I have been editing as a "hobby" since late 90s..and can tell you that one thing that rocks with them is they are consistent and are always exploring new territory in design and structure, I have used other editing programs and premiere always keeps the core basics at home, you take a program like final cut pro which I fell in love with then watch them go full on final cut pro X to something that is absolutely absurd to what you are familiar with as a change over and damn to some that is fine...I don't know, I do know that anytime I have a problem in premiere, there is always an answer, which...is why I am posting here. My latest dillema as a video hobbyist is going full 4k, well it takes a lot of everything, which is why proxies are so important, I would be shocked if I didn't find an answer to my solution in how I can do so moving forward. Premiere is consistent with its tools and resources, and I would only be back peddling going to another program and truly believe it is built on heart, even if I think they have zero clue of seeing what should be the main focus in 2019 for video editing with proxies for people broke as me that are into this as a hobby. I say stick around and adapt,the core of the program is still built on heart and soul.
