New build advice around RX 7900 XTX

Currently running on a Ryzen 7 3700x \ 5700xt, build is 4 years old at this point, capable but ive got the upgrade itch and some new titles I want to get the most out of coming soon,

Will only ever use it to game,

My thinking is to base the build around the RX 7900 XTX, the 4080/ 4090 are possible top but ive always been an AMD fanboy and I would need a substantial difference in quality to move away

So my first goal is to find a CPU that doesn't get bottlenecks by the GPU, which leads me to Ryzen 9 7900 12 core 5.4ghz, but I am open to suggestion,

I'm planning on keeping my current rig for VR in the lounge, so I won't be keeping anything from it, and aside from having components that keep up (sufficient size\speed ram, reliable and beefy enough PSU) I am not into RGB for a premium or displaying my PCs internals so the case and other components are much more function than form for me... could be an ugly metal box and that suits me fine,

Always clueless when it comes to mobos, just need something that fits the CPU slot

Ive always gone with fan cooling, wouldnt be opposed to water cooling but fan noise is of zero concern to me so often i found the finkecy build complications of a water system were never groundbreaking enough to replace a good heating

RAM should be more than I need but not by much, convention seems to be 32GB now (am I wrong)? So maybe consider going 64GB for some overhead future proofing

Don't care if its SSD or M.2,, a good 4-10tb of storage is likely on the menu but im fine enough figuring that out for myself

Case is irrelevant, should just fit the parts

I'm just a bit unsure if the CPU is good enough or overkill
I'm also unsure if me sticking to AMD is suitable here, benchmarks put it 3rd behind 4080 and 4090, but I don't see enough must have in those cards versus this one, am I wrong?

And id take great benefit and would appreciate it very much if someone had advice on how best to build this, ive greatly appreciated the help ive been offered before and would love to lean on that again if someone might be so generous to spare the time?
 
What exact motherboard are you running? You're probably best off just upgrading to a 5800x3d and 32gb of ram on your current system.

If you absolutely require a new system as mentioned am5 with a 7800x3d is your best bet.

I'm not opposed to keeping what I have, and I have a MSI b450M gaming plus, which being AM4, but are you suggesting keeping my CPU? Unless I'm missing something, my current CPU will be bottlenecking my GPU quite a lot and I need to upgrade the CPU too

And if I'm doing that, why not just build a new system and utilise a 2nd rig for VR (which I don't use right now because of space, that isnt in my bedroom gaming setup but I have space in my living room)

Open to options, and not opposed to spending to get the job done,
 
A bios update will allow that motherboard to run a 5800x3d, which will pair well with any current GPU. Upgrade to that CPU and 32gb of ram and you're good to go for a lot less money than an entirely new platform.

My basket at OcUK:

Total: £407.98 (includes delivery: £7.99)​

Awesome suggestion. However I am still thinking about what I can do for a new rig.

A lot of reviews I am seeing suggest 5800x3d is negligible in difference for 1440p gaming vs the 7800x3d, so im leaning to making a build around 5800x3 and the aforementioned AMD card

Are there any obvious pitfalls (other than the mandatory power matching for a PSU, clearance height for case vs cooler, ram compatability) that I should be aware of with a system like that?

And for ddr5 ram, is 6000 speed needed or is that overkill for gaming?

This is the build I knocked up, not sure how effective it is?

PSU, good for the power profile I have or do I need more? Gold rating still good?

RAM, £200 seems a lot for 32GB ram, am I overspending for the speed or is that going to make a noticeable difference?

Cooler, looking for a heatsink that has some beef to it, good enough?

Case, good fit for the Cooler and not going to be squashed in?

Mobo, don't think I need any bells and whistles, so is this good for my cpu and other gear?

4TB ssd, this m.2 looked good, well
Priced, im not going to suffer on speed and by paying a bit more am I better with a different m.2 or ssd?

No monitor in the build

OS is covered

Am I missing anything else (aside from some extra fans which I'll wrangle)?

What is the judgement on the above? Any good ways to spend my money better either with adjustments in the build to save or by spending more for an improvement?

Not a fan of spending a lot more for no real benefit and it's negligible to drop a Tier in something, but the flipside is true too, if I can upgrade for a little more and get a substantial benefit, I will do it

Happy to spend 2-3k on the build, maybe more if its worth it
 
Memory: I'd swap to the kit I suggested, especially if you're getting a X3D that doesn't care.
Cooler: I'd get this, it's much cheaper and pretty well tested on here at this point. The X3D is a very efficient CPU so power consumption is low, see here.
PSU: 650 is rather puny for a 7900 XTX. I'd recommend a ATX 3.0/PCIE5 PSU, but you have to be careful because you can end up with not enough unique 8-pin PCI-E connectors for a 7900 XTX, especially if the motherboard needs 2 EPS 12v. For this reason, I usually suggest MSI's non-PCIE5 version of the A1000G, which is reviewed here:

This is an 'affordable' alternative, but as I suggested, you'd need to check the connectors are enough first:

SSD: if this is for an OS, I don't recommend it.
Yeah I heard from a few reviews the CPU doesn't really care if it is 5300 CL30 or 6000 CL30 so that's a good shout

thanks for the shout out on the cooler, will take a look

So for a 1000w psu, the one you recommend (a1000g) looks good, will seriously consider that, especially as you recommend it is compatible with connections

For SSD, it's mostly going to be gaming so fast load times etc. Don't need to worry about super fast transfer speeds but I'm a bit green when it comes to knowing what is important for a gaming pc based SSD

Thanks lots of useful info
 
Thanks for all the advice, just snatched up the parts I need (thankfully I could get good stock and pricing on the cpu, gpu and case at OC), rest via Amazon which included the PSU recommended, the recommended thermalright PA cooler, went with a WD Sn770 2tb m.2, corsair 5600 CL36 vengeance 32gb ram,

Amazon had better or equal pricing on the GPU and CPU but the lead times were hopeful rather than reliable and id rather pay a bit more to get everything coming to me within 1-2 days. Nothing worse than hanging around for required parts for weeks!!

Came in total around £2,100 ish which is a dream considering that during the GPU price issues a year or so ago, I was looking at a top end machine for 3k+

All help appreciated
