McFly ?
So nice you bought it twice

I may get one when I'm forced to move to Win 11 in a year and do a fresh OS install plus by then the price will hopefully be better. The reason being, I'm laziness. And moving from 6 cores to 8 ideally requires a fresh Windows install or there can be issues (Windows may not correctly manage all the cores in games/apps).
The 7800X3D real world power/temps are actually really impressive and not all that far off my 7600 non-X so I'm sure it'll be fine. Plus I think we're done with CPU temps now aren't we? It's plug and play and if it's less than 95C it's in spec.

Wait I'm upgrading from a 7600x to a 9800x3D. I had no idea core counted meant a reformat. That will be a pain.

I've never seen that previously. 1CCD to 2CCDs I've seen people suggest being worth a refresh.Wait I'm upgrading from a 7600x to a 9800x3D. I had no idea core counted meant a reformat. That will be a pain.

Never heard that, I’ve gone 1700, 3950x to 5800x3D without refreshing my win10 install and no issues.
Also work wise changing core count in VMs is a common occurrence and never reload the OS, reboots at most, even windows vms.

Yeah, here's where I heard it https://www.techpowerup.com/review/amd-ryzen-7-7800x3d/28.html and also Level1Techtips. It may be patched with a BIOS and Windows update by now though, not sure.Wait I'm upgrading from a 7600x to a 9800x3D. I had no idea core counted meant a reformat. That will be a pain.
It works, games will run, but if you look at the core usage, it's funky. ok so that was 7950X3D to 7800X3D in that case but that's enough motivation for me to do a fresh install!
I love these temps on the 7800X3D and will go straight to that page on the 9800X3D review

It's generally not a problem
But that's not always the case - some modern CPUs have custom bits of software in windows that can stick around even after swapping cpu. With Intel you may have APO or thread director and with AMD there can be power profiles and thread scheduling variances between single and multi ccd chips that can sometimes stick around when they shouldn't, leading to performance degradation when changing CPUs - this recently happened to reviewers when they were swapping the amd 9950x in and out of their systems, and it also happened with the 7950x3d

Almost certainly going to order a 9800X3D when I can.
Do we think I might need to consider upgrading my motherboard and RAM (thinking X870E and 8000 RAM ..... ) or will it be minimal difference. I guess we wont know until the benchmarks appear.

Minimal difference. 6000/6200/6400 is the sweet spot because you want to keep sync with the Inifinity Fabric. Higher speeds are possible but largely pointless.
You can get the max out of 7800X3D and 9800X3D with a £100 B650 board.

Unless you're desperate for USB4 I'd keep your current mobo tbh m8, no other differences really. Also DDR5 6000C30 nice and tight seems to be the sweet spot for gaming so it looks like you're all set.
I'm personally not bothering to switch, the gains will be v minimal at anything past 1080p.

No need to switch motherboard and ram, the difference is nothing.
We've known this since Zen 5 release. Other than the X3D cache, the 9800X3D has no other architectural changes over the other Zen 5 SKU's. It'll still run ram exactly like the other SKU's do.
And we've been seeing for weeks now what those can do.
AMD DDR5 OC And 24/7 Daily Memory Stability Thread
www.overclock.net
C6000-6400 with tight timings is easily doable on just about any board out there. The difference with 8000 ram is pretty much nothing.
You also want to be running the IF at 2100+ for another easy perf increasase (be warned not every CPU can run over 2167 with stability. 2133 is doable by the vast majority of AM5 CPU's)
DDR5 Memory Performance Scaling with AMD Zen 5
Our AMD Zen 5 Memory Scaling Review examines six different DDR5 memory speeds, including DDR5-8000, DDR5-6400 1:1, DDR5-6400 CL28 and others. We looked into how these speeds impact performance in gaming at four resolutions and a wide range of application workloads.

Being on Intel and moving to AMD after so many years feels weird! Looking to upgrade my 9900KS with the new X3D chips (possibly the 9800X3D, maybe the 9950X3D as I use my PC as both a workstation and some slight gaming). If money isn't part of the equation, what would the best Motherboard + RAM combo be in the AM5 world w.r.t best MT/s (I'm comfortable with OCing) whilst having in mind I have 2x Gen4 NVMes and looking for NVIDIA's new GPUs with PCIe 5 come 2025? According to HUB, it looks like the Asus X870E Crosshair Hero is the only one to reach 8400 MT/s?

you could do worse.

700 ish USD for that baby (9950X3D) or more.

AMD Ryzen 9 9950X3D release date, price & pre order details
AMD Ryzen 9 9950X3D release date is now just around the corner, with early 2025 looking like the likely date for your diary.

Thats a trotal guess but even so value is a matter of perspective. If as fasst as 9950X in productiity (or within a coupe percent) and a good chunk faster in games then it will sell wellyou could do worse.

Ram speed doesn't really matter. Chasing MT/s for the sake of it is a fools errand. 6000-6400 is all you need for AM5 processors.
Just pick a board with the features you want most.
That's a nice workstation / creator board, has a lot of features for the money. Just dont put a drive in the M.2_2 slot as it will drop the PCI-E lanes on the top PCI-E slot to 8x
Will perform just like any other X870/E in gaming.
Does the work you do benefit from more cores?
Have you not considered a 9950x? Unless the work you do gets a boost from the cache on X3D SKU's, the 9950x will have a slight edge over the X3D.
Gaming wise the 9950x is only marginally worse at 1440p and above.
At 4k there's pretty much nothing in it other than a handful of outlier games that can still benefit from cache

just watched this one.
9700X
what can i say. It becomes an obsession
$700AUD for a 7800X3D here. I suppose it would run on a B650 board. I'm convinced. Even that is above my usual limits. but I see the appeal.
