New build and out of touch, any real difference in mobos between x670 and b650e for gaming?

Been a good few years since I've built a PC and just wanted to check I'm not totally out of the loop. Was looking to put together a high end build as now have the time and money to put it to a bit of use. Only real stress for it will be gaming, have a G9 monitor so 5120 1440 at high FPS is basically what will be going for, mainly first person shooters and the occasional simulator. On the motherboards, going with AMD for the 7800x3d and MoBo might get another generation but not sure why they have got so expensive, am I missing anything in b650e v x670, I don't need multiple PCIE devices and wont need a million USB ports but is there anything major different apart from some additional PCIE lanes? B650E seems to have everything I would need and room for any realistic changes in next couple of years or am I wrong? Then RAM I am assuming isnt such an issue with the 7800x3d. Also want it to be quiet, but is the silent loop overkill. Then finally I could go top end GPU but also slightly amused/amazed that they are now £1600+, I am assuming at 5120 x 1440 a 4090 is just a waste of time. Have left out case and power supply as not sure on GPU, and open to suggestions, no interest in looks/RGB more focus on quietness/performance.

Yep going to DIY it. Had been thinking it would be ~£75-150 for the case but if there are towers that make it easier/quieter happy to spend more as case is probably the one part I wont be updating for some time as not too worried about aesthetics more the functionality (although having done a bit of looking at the dimensions of some GPUs, seems like will need a small cupboard for the next gen if things keep going the way they are).
 
only diff between the B650E and the X670E is the X670E chipset is basically 2 of the B650E chipset, so you get more lanes and more usb 3.2 gen2 or whatever the board manufacturer wants to do with the extra lanes. The E denotes pcie5 gpu and nvme slot, but that's also not a requirement, more a recommendation, so you really need to go through the boards to see what they have. Been looking at the asus B650E-e v the x670e-e myself. prefer the e variant to the f as i like the debug display which will actually give you some codes telling you what's wrong, rather than a led light that could mean anything.
VRM's, B650E-E has 16+2 70a, x670E-E 18+2 110A...the 7800x3d doesn't draw that much power so massive overkill on both, and should offer plenty of power for future cpu upgrades...B650e has 4 nvme slots, 2 are pcie5 speed though drops to pcie 4 if you use sata ports i think(4 ports)...x670e-e 4 nvme, 3 are pcie5, 4 sata,..x670ee also has a start button on the board so you can test it outside of the case, and guess more rgb on the heatsink...anyway, you can see below

Also seen the 2tb crucial P5 plus for £132 on offer if you search, which is step up from the P3 plus above...they also have non rgb corsair 32gb 6000c36 veangeance for £108
Also b650e-e is on offer for £305.59 with free next day delivery

Below is a review of the B650E

and the x670e-e

for roundup of x670e boards though below nice starting point before you delve deeper

total for the whole computer setup sans peripherals

it's easier to spec and balance a build if we know the full budget rather than speccing piecemeal

Ta, wasn't sure. Had assumed ~2.5k and could stretch that which I know can get top end spec, but I am not going to be trying to push out 4k, or doing any heavy rendering and don't feel the need for the latest and greatest. Would like a machine that will handle current batch of games and probably the next set, be upgradeable down the line and that can play current batch of games at 100+ FPS (although while not quite 4k I do use a 5120*1440 monitor)

Thanks, that is v helpful. Does seem like anything more than the B650e e would be beyond what I would need anytime in the next few years.

much more than that. it's an absolute waste of money

I specced this build for someone else but easily customisable to your requirements...more to show that you don't have to spend that much to get a decent system
AM5 is supported through 2025 so room for upgrades without changing mobo
7900XTX is a 4080 equivalent with much more VRAM (but less CUDA and worse ray-tracing) easily swappable to the 4080 if you wanted

honestly though with 1440p super-ultrawide, the pixel count is not too far behind 2160p (4k) - 7.4Mpix vs 8.3mPix - so if you're really out for max performance then you should really get the 4090
if you're happy to turn some settings down then a 7900xtx/4080 should be fine

depends how future proof you want...for current gen, pcie4 gpu slot can handle a 4090, so if you're putting in a lesser card and plan to upgrade in a couple of years to 4090 performance, then pcie4 is all you need. If you're byuilding a 'high end' gaming rig though and plan to get a high end gpu a few years down the line, then you'll want pcie5 gpu slot. rumours already circulationg a 5090 card will be twice as fast as a 4090 and it'll be pcie5 as will exceed the capabilities of pcie4...prob wont be much of a hit but when the 3090/3090ti came out, a lot of high end builders where chopping in their pcie3 x470 boards as they were pcie3 and didn't want to take even a small hit on perfomance when splashing out £1300 to £1900 on their gpu's, so an extra £100 making sure a mobo is pcie5 with pcie5 nvme becomes fairly irrelevant over the full pc build cost.
Me personally, i want the debug display on my next mobo..got it on my present one, and don't want to loose the feature..that ands I want a pcie5 gpu slot as might skip this gen gpu and keep what I have and then go 5090/8900XTX equiv down the line, though may cave on that, haven't decided yet. Samereason prob get a 1000w psu again..lasts 10yrs under warranty, generally v efficient now at low % utilisation, and hopefully should cover future upgrades without having to swap it out..extra £30 now gives me peace of mind

only a few % difference between gen3 and gen4. i'm sure whatever the 5090 will be, gen 4 should be okay.
i quote one of the comments in the video which echoes what my opinion is: "benefits of pcie gen 5 is more about being able to use less lanes for equal bandwidth. Gpu's who use 16x slots shouldn't see a real difference"
basically the "futureproof-ness" of a pc has to stop somewhere depending on the budget...in my opinion, pcie4 should be good for the next few years whilst AM5 remains relevant (ie top-end) for gaming

Fair enough I guess...lets say 3-4% loss with 4090, so on a £1600 card(if you get a fe) that's £48 to £64 wasted performance. Who knows what diff is on a 5090 or above for future upgrade down the line.
So yes, you can go cheaper a la riptide etc but still like a bit more premium (myself) if going for top end build..whole point of going top end, and try and future proof yourself as much as poss(no one know future, look at gpu's and vram..not many people talking about that a few years ago)
Still, debug is something I like and want, but maybe OP doesn't, but seeing as he put the b650E-E and not the B650E-F which is cheaper, maybe he does. Also, the vrm's are better on the more expensive board, so it should run cooler, so therefore should be ableto run fans at lower rpm, so quiter..also sound codec is better too, if that is of interest. Too me, it's worth a bit more, but can't argue with your price point if just want best bang for buck
One thing to note if going smaller form factor (for OP) is generally the smaller boards have less nvme slots, so factor that for future upgrade storage expansion, and if going fort micro case, check size of gpu slot..4090 are large(if going 4090) and a lot of cases can't fit them, or they just fit in which case you can restrict free airflow around them
other alternative for the riptide if don't mind the pcie4 gpu slot would be the gigabyte gaming x ax...atx board so get 4 nvme slots, and actually in HU box test, riptide was 9% slower, though with bios updates, maybe that's been corrected..you have to unlock the thermal limit on riptide which is locked at 75degrees out the box..good test of the cheaper b650 boards below..prices have changed so worth looking around as everything fluctuates


if you want a good chuckle this is one of my fav vids from gamernexus 'Jesus'. Made me laugh anyway, esp when talking about Asus and 'For those who Dare', and MSI for ....

Another good case I like, is the Lian li 216. It's basically a longer 215, basically designed to take the bigger 4090 cards. Has excellent airflow, and 4090 cards being over engineered originally as thought they might need 600w cooling power, generally run silent from most of the vids I've seen. Anyway, cases can be very subjective, so worth looking around

don't forget this is gen 3 vs gen 4, if there's only a minimal difference between them i think we can extrapolate that a 4090 is hardly saturating gen4 x16 bandwidth

i suspect a bit of a moot point as by the time gen 5 (ie when gen 4 x16 becomes saturated and truely a bottleneck) becomes relevant for gpus, AM6/AM7 would be out by then
case in point would be AM4 + gen 4, this came out in 2019 with the ryzen 3000 series, i would call you mad if you recommended anyone to run a 4090 with a 5800x3d much less with a 3800x lol
