My System is currently like this which I have built on 2020

Motherboard: MSI MPG B550 GAMING EDGE WIFI 5100MHz(OC) DDR4 AM4
CPU: AMD Ryzen 9 3900X 3.8/4.6GHz AM4
GPU: MSI GeForce RTX 2070 Super Gaming X Trio 8GB GDDR6
RAM: Corsair 64Gb (4X16Gb) Ddr4 3200Mhz Cl16 Dominator Platinum Rgb
Cooling: Corsair H115i RGB PLATINUM 280mm
Power Supply: CORSAIR AX850 850W 80 Titanium

Honestly, I don't want to invest in AM5 yet. I think I'll wait until AM6 period. I want to wait for another 4 years before investing on a large upgrade.

I bought Ryzen 9 3900X at that time as I was doing a lot of rendering/video editing, too at that time and it's still doing it's job perfectly and I'm sure in terms of rendering and video editing Ryzen 7 5700X3D will be a downgrade.

However, since I'm not doing video editing on that PC anymore, I'll focus more on gaming and I feel like Ryzen 7 5700X3D would be the best option while staying around AM4 MoBo. I would love to get 5800X3D but unfortunately, it's not available in the market anymore.

I generally play MSFS 2020 and I may try MSFS 2024 soon after they fix the bugs :)
I also like to play open world games like GTA, RDR etc but mostly MSFS.

Your thoughts are important for me...

What do you think? Should I upgrade to Ryzen 7 5700X3D? Will it create a difference with my current GPU?

I'm also planing to upgrade on GPU but in 2025 only.3900x vs 5700x3d
