That honestly depends on a few things. Current release is the X3D side of Ryzen 9000 series CPUs.
It's a newer X3D technology compared to something like the 5800X3D or 7800X3D.
A few years ago I started to depend on an Athlon 2650e for network storage, a single core AM2+ relic. Took a week to tame but it works great.
That was a
fast system 16 years ago and makes for a very slow server but a borderline unusable workstation today.
I'm just spitballin here but I'm guessing you want to actually
use the computer for multitasking, gaming, etc.
For nearly a decade of CAD and gaming I've been on a Phenom II X4 955BE, an AM3 era chip paired with 4GB and an abysmal HD6570 2GB.

At $245 the CPU was worth it. The memory kit was the worst possible pairing and I eventually switched up to an 8GB Ballistix kit.
It took until a heavy interest in VR to figure out the HD6570 was causing serious instability, audio stutters and rendering issues in DX11 titles.
It is extremely important to pair your CPU with a competent GPU or whatever accelerator you're using for this and that or the system WILL struggle.
During peak Ethereum mining I made the expensive but correct decision to switch to a RX 580 Red Devil, which I still use today.
At this point everything looked good except I still needed a better CPU and memory was maxxed when loading certain VR worlds.
So mid-2018 I changed up to the FX-8370 and a 16GB G.Skill kit.

This CPU was also worth it but shortly after, the price shot off to $400+ so I couldn't recommend it to anyone. The memory kit (still) kicks ass.
8 cores is not spectacular but this made the difference. It was triple the performance with ALL the extensions.
All of them. 8MB L2+L3 cache helped.
The breach into the 4GHz clockspeed barrier was also huge, which I desperately needed for some games even though this chip isn't what we call
efficient.
It's also worth noting, this CPU paired perfectly with my RX580, so beyond this point, there were zero improvements to GPU usage.
A year later I picked the R5 3600 and an Asus X570 TUF board.
The RX 580 is still a weak pairing but is without successor.

A sub-$200 6c/12t chip is a weird change but good. This is also where I started to notice some trade-offs.
It is 2x the performance of FX. My games have not improved under this even with my insane overclocking abilities.
In some cases games perform worse but it does great in Folding@Home and other crunchers where the FX falls flat.
It may have a future after I retire and rack it as a new video/streaming server because it is more x264 encode capable.
However with a MX standoff between the nvidia Tesla P4, RTX A2000 and low profile RTX 3050, I may just go NVENC.
With all of that in mind, the 5900X is kind of my target upgrade from this 3600 and yet I still see no real reason to make the jump.
You are on a 5900X and looking into the 9800X3D, which is pretty wild but my fav streamer picked up the 9900X3D this week and it's solid too.
There's a great choice of AM5 CPUs available but I don't see anything exciting or other-worldly about the memory kits. I'm an easy romance too.
My 3600 handles gaming, 3DVR, batch rendering, streaming, virtual jobs, containers and video editing just fine for now. Is it my OC? 64GB? We don't know.
If a 9800X3D is in my future it would be the
far future. There's nothing wrong with any of that but that's where I'm at.
I make very BROAD jumps between CPUs. Mainly 5 years apart (in design) and we're already in Feb of 2025. So who knows?
Maybe I should be looking at the 9800X3D. Not like I need it. There's a good chance you don't need it either but it's
fast af boiii.
5800X will still be fine for a while
