Question I need help upgrading one of my two computer builds.

[TooMuchViolence]

I have loved video gaming since the 1970s, and this will probably be my last gaming system. I have very limited funds and want to make every penny count.
I wasn't planning to buy the PlayStation 5 Pro, but I am considering upgrading one of my PCs for gaming and video editing with 4k resolution
If any mix-and-matching can improve one of these computers, then add a video card, power supply, and RAM.
What is the best I can achieve without using water cooling? Monitor is- QNED80 Series 50-Inch Class QNED Mini LED Smart TV 4K Processor Smart Flat Screen TV for Gaming
Here are some short questions:
What is the best video card I can get based on my current setup? Should I add more RAM, or is the RAM I have already outdated?
I am willing to spend between $600 and $1000. I would really like to experience the best in computer gaming, but that seems out of my reach. Thank you for any help you can provide.
I have two computer builds. One was way back in 2018 (I had more money to buy latest hardware). 2nd build was in 2022 and I had a lot less money. Both computers are running win 11

Thank you to everyone who has helped me with this. After doing further research, I've decided that, given my budget, I will likely choose a resolution of 1440p with higher frames per second. If you would like to change your recommendations based on this decision, please feel free to do so. Thank you once again!

Even for 1440p, my recommendations still stand.

It might be prudent to (if you can) wait for soon to come new GPUs from Nvidia (50xx) or AMD (8xxx) which are supposedly going to be faster and cheaper, Other than that, those I suggested should be enough.

Upgrading first one is only one that makes any sense, just ad a mid range GPU and you are all set for gaming. Since 10th/11th generation, Intel didn't make big upgrades and that one of yours is still capable CPU. Don't have to go crazy with GPU, for money you allocated you should be able to get RTX 4070 or Rx 7900xt and have some left for an NVMe SSD while not having to change PSU. With eventually only some conservative settings, should be able to enjoy gaming for some years to come.

I read that some of the i9 processors are experiencing significant issues. I believe that following the COVID shutdowns, the quality of many products has decreased while prices have increased. However, it seems that normalcy is starting to return. I also read that the new Nivida 50's will be out in January .

Based on my research, I’ve found that Nvidia is better suited for video editing. As a hobby and in memory of my late wife, I plan to create a YouTube channel dedicated to her. That’s what inspired me to start this project. Now that I have run out of games on my PS4 Pro, I figured why not make it a gaming rig also.
