I currently have a B350 AM4 (Asus Rog gaming b350-f) that actually supports rebar,with a 5900X and a 9070 XT. Is there any point to upgrading to a newer AM4 board (and hopefully seeing some improved performance) or does making the jump to AM5 make more sense? A platform swap would be a major investment…

Do your needs exceed the speed capabilities of pcie3?
I guess that is a major part of the question. Given the CPU and GPU in question, would there be any noticeable performance increase?
I do not have any storage devices that would come close to saturating PCIe 4.0.

A previous-gen Zen 4 + B650 setup could be much more effective than trying to source an AM4 motherboard, if cost is a factor.
What do you use your system for?
I play games at 1080p 60hz. Pcie3 is plenty for my needs. I dont do any of that cuda or ai or crypto bs.
My monitor is 1440p @ 360Hz so there’s plenty of headroom for improved GPU performance. But would there be? That’s what I’m not sure of.
My ‘workload’ is mostly gaming, along with some video editing and the occasional need to compile from source.
Doesn’t sound like it. If you put a PCIe 3.0 NVMe in a PCIe 4.0 or 5.0 capable M.2 it continues to run at 3.0.
There’s little real world PCIe scaling data for NVMes and I don’t know of any gaming test that’s stayed consistent across PCIe 3.0, 4.0, 5.0. But what is available mostly indicates for single digit percentage reductions in load time for gen to gen, maybe approaching 20% for 3.0 → 5.0 for some loads in some games.
Possibly. Alder Lake’s been having issues benching full rate 5x4.
