CPU upgrade help

[austind903]

I bought the RTX 4080 GPU and I’m wondering if I need to upgrade my Ryzen 7 3700x CPU. I use my PC for computer science coursework. I run a couple of virtual machines, and gaming at 2K/144fps. I'm considering the Ryzen 5 5800X3d, Ryzen 9 5900X, or Ryzen 9 5950X CPUs My motherboard doesn't support the AMD 7000 series.

 

If any of these CPU’s aren’t worth upgrading, should I better off overclocking my CPU? I have a good 360mm AIO cooler. 
 

Thank you.

Zen 2 will definitely bottleneck a 4080 in certain scenarios some of the time, that being said, like always, if it does what you want it to do as in performing to your expectations fps wise and programs wise, I wouldn't mess with it. Choosing the right cpu will depend on rather you lean more towards gaming or more towards work related tasks, the 5800X3D will be the fastest gaming wise, but it'll lose ground in work tasks just based on the core count vs the other processors you've listed. I'd use the system as is with the 4080 and see how it performs. If it isn't up to snuff for you then consider your options and what you think will give you the most value for the tasks you mainly do.

 

As far as overclocking goes, it won't make much of a difference with Zen 2. Zen 2 still had the split CCX design and no amount of clockspeed you'll realistically hit will make a difference worth noting. Zen 2 's weakness is the core to core latency as a result of the split CCX/cache design. Most of the time it isn't a problem but you can run into cases where the latency between cores just limits the maximum amount of performance/frame rate you'll be able to achieve.

Ah okay, 5800x3d is basically the best out of the three for gaming. Yet, the core count is going to be the same as the 3700x. So if I want the best of both worlds for core count and the core speed, maybe the 5900x might be the choice? After looking up the 5950x, it’s pretty expensive I found on Amazon for ~$470 compared to the 5900x is ~$325

i can't recommend the 5900x or 5950x, 5800x3d would be the choice here.
