Build Advice Best CPU upgrade path for an RTX 4070 setup ?

[arnerino]

I'm looking for some advice on upgrading my PC.

Right now, I'm running an older Ryzen 5 5600X overclocked to 4.5GHz. I've got 32GB of DDR4 3200MHz RAM, an NZXT N7 B550 AM4 motherboard, and a Kraken AIO cooler. My PSU is 850W and I have an M.2 SSD, so power and storage shouldn't be an issue.

Last year, I bought an RTX 4070 Founders Edition, and I’d like to build the rest of my setup around it. Since I’ve already invested in a solid GPU, I want the rest of the system to match its performance. I mainly play CS2.

I'm unsure whether it makes more sense to stay on AM4 and upgrade to a used Ryzen 7 5800X3D, or to switch platforms entirely and go for a new CPU, motherboard, and DDR5 RAM — possibly a Ryzen 7 7800X3D or the newer 9800X3D.

Hoping some smart folks here can help guide me in the right direction!

My PSU is 850W
850W is the advertised wattage of the PSU, what is the make, model and age of the unit?

How much are you willing to throw at your proposed upgrade path? How much does the 5800X3D go for where you're located? If it's just CS:GO2, you merely need to look at a processor upgrade. If what you do puts a roof over your head and food on the table, then you migrate to an AMD Ryzen 9000 series platform.

One last point, would be good to pair a 2x16GB DDR4-3600MHz tight latencied ram kit, would bring the best out of your B550 platform.

Thanks for the response!

My PSU is an NZXT C-Series Gold C850, and I bought it about four years ago.

As for budget, I’m open to spending whatever makes the most sense. Money isn’t really the issue here — I just want to build something that complements my RTX 4070 the best. If the performance difference between a used 5800X3D and a full new 9800X3D setup (CPU, RAM, and motherboard) is minimal for my use case, then I’d likely just go with the 5800X3D. But I’m mainly trying to figure out what the smartest choice is in my situation.
Where I live, I can get a used 5800X3D for around $375.

CS2 really benefits from the additional cache so a 5800X3D is going to perform pretty well:

As for what the smartest choice is going to be that totally depends on what other stuff you do with your system. The 5800X3D is going to be slow in non-gaming workloads and won't beat 13th/14th gen Intel or 7000/9000 (non-X3D) AMD in some games, but if CS2 is the majority of what you do that might not matter.

Platform wise (first of all they're all better than what you have):
I don't think AMD is going to be doing anything revolutionary on AM5 until after Zen 6 since the 600 and 800 series chipsets are identical. LGA 1700 is better in some ways (ex: chipset connection is PCIe 4.0 x8 instead of x4) than AM5, but also worse in some ways (ex: cannot use PCIe 5.0 SSDs without compromising primary slot lanes) so they're a pretty even tradeoff. Intel has the best client platform with LGA 1851, but I would never recommend it to someone who just games.

Overall if there's nothing about moving to a new platform that is going to impact your typical usage in a noticeable way it's probably not worth it.

5800X3D keeps 1% and 0,1% lows pretty high in cs2
(and those are more important in this game than average fps when it comes to overall smoothness)
(anything short of 7800X3D would not be better in this regard) .

but as pointed above this chip is not great in cpu heavy applications
as long as you really need this just to play cs2 and do some light workload tasks on it
than 5800X3D and 3600MHz/cl16 memory is your cheapest and best option .
otherwise it might be worth it to consider AM5 platform .

Could also look for the 5700x3d. Should give most of the performance of the 5800x3d but might be a little cheaper and more available.
