Hi! I've being using a 2700X + Vega 56 + 16 GB 3200Mhz build for the last 5 years and I'm considering an upgrade 
Use? Gaming. I mostly play "competitive" games in 1080p 144hz monitor but I eventually may change to 1440p monitor (not right now), also I casually play some AAA games (RDR2, etc) on high settings (I really don't max settings)
Here's the thing. As I've a AM4 gen setup, I could upgrade some parts of it... But, is it worth? Let me explain:
Upgrade costs ~$1752
To me it's reasonable to go with the new PC:

Upgrade costs ~$1752
- CPU: 5800x3d (need to flash bios of my x470 mobo) [~$545]
- GPU: RTX 4070 [~$1027]
- PSU: 750W Plus Gold (I'm using a 650W Plus Bronze)
- Cooler: AK620 (currently I've the stock wraith prism air cooler)
- CPU: i5 13600KF [~$406]
- GPU: RTX 4070 [~$1027]
- Mobo: Gigabyte Z790 UD AC [~$349]
- RAM: 32 GB DDR5 5600Mhz [~$100]
- PSU: 750W Plus Gold (I'm using a 650W Plus Bronze)
- Cooler: AK620 (currently I've the stock wraith prism air cooler)
- Case: Corsair 4000D Airflow
To me it's reasonable to go with the new PC:
- For similar price, I'll be on a "new gen" (though it'll be "outdated" in next few months on 14th gen release)
- More "future proof" as it'll be using DDR5 and some leaks are saying that LGA1700 will support 14th gen
- Based on some CPU benchmarks there isn't a great performance difference between both build
- I'll be comfortable for the next 3/4 years at 1080p and probably 1440p
