I’m going to buy the AMD Ryzen 7700X cpu

[Citizen Cook]

I’m going to buy the new AM5 cpu when it releases later this month as part of a new build. What motherboard would be best to pair with it?

Isn't PCIe 5 overkill for single m.2 ssd and GPUs?

It's far overkill for graphics cards for gaming outside of fringe cases, such as being out of VRAM and dipping into shared system RAM overflow, in which case performance is suffering anyway.

It's mostly useless for storage for "general" consumers, but at least has a use for prosumers, content creators, and those dealing with shuffling large data/files around.

The non-E boards will be fine for most people. You'll know if you need it.

Do you foresee a time when a gamer will need PCIe 5 on AM5 for a GPU or M.2 drive?
Or will it remain overkill for the entire socket’s duration if all someone is doing on it playing the latest games?

[Heretic]

I wouldn't concern yourself with the pcie bus, anything modern will do for the foreseeable future. Even good pcie 3 nvme drives are more than enough for most people.

No, by time PCI-e 5 becomes a necessity, we'll be on PCI-e 6 or 7. If not on a new slot design entirely. It's always been like this, 2.0 lasted a long time, 3.0 is still viable, and it'll be more than 5 years before 4.0 means anything.

Trying to predict the future is often a bad idea, and the best we can do is extrapolate from current trends. Going on that, PCI Express version is almost a non-factor you can ignore.

There's only two things I can think of where things may change regarding impacts of this.

One is the increasing case of some GPUs using less lanes instead of the full 16 lanes (mid-range and above GPUs are, hopefully anyway, unlikely to have this occur). PCI Express version times number of lanes equals bandwidth.

The other is direct storage, and I don't know anywhere near enough to say anything about that one.

Ok, so it’s said that the NVMe inside the PS5 is incredibly fast. Can anything on the PC side match it, if if it can, does it use PCIe 3 or 4?

Ok, so when I buy my board, what SHOULD I be looking for if I want to future proof it (as best as humanly possible); remember this is a gaming only PC, no streaming, or video editing or any of that jazz, I just want to play the latest AAA games for years to come and not be restricted by my board. So to start, I’ll put a 4080 in it and 32GB of DDR5 RAM and a few years down the line probably replace the 4080 with a 6080 and double the ram to 64GB using all 4 lanes, and pop in the Ryzen 9700X.
I know this sounds a little crazy, but I’m trying to by a board that I can get 2 builds out of, one this year, and another towards the end of AM5’s lifecycle.

RAM doesn't use PCI Express lanes.

64 GB of RAM is unlikely to be anywhere necessary for games even two to three years from now (unless you're playing something like Cities Skylines or something else that is singularly known to actually benefit from it). Outside of some edge cases, 16 GB is still sufficient on the whole today (though for a new system build today, yeah, I'd be buying 32 GB). 32 GB will still be good five years from now (personal prediction, but probably not a stretch). I say this because you'll likely be adding 32 GB to it years from now, so you're possibly better off buying what may be faster RAM and staying with 32 GB, or just staying on your original 32 GB outright, either way.

I wish I could tell you what board to buy, but I can't make that choice for you. You're going to have to make a choice regarding spending extra money for features you may or may not need in the time you use it.

You have to consider that a new "decent" board when you change over to Zen 5 might be something like $200 to $250 or so, so if you're spending up on a higher tier board now that comes close to that amount extra, is it really worth it then? I'd say no. You also more lock yourself into AMD. What if what Intel has at the time Zen 5 comes is a tempting consideration? Socket longevity is a great thing, but I would still just accept it as a bonus, buying what you need now, and using it until it's no longer good enough. Otherwise, when you're sort of planning your upgrade after your next, you're sort of setting yourself up for stuff like this.

Nobody knows what's good and what isn't yet because they aren't out to be reviewed. Boards can look good on PAPER but they can end up being garbage due to faults.

X670E or B650E, they support PCIe 5.0 for both graphics cards and storage.
X670 and B650 support PCIe 5.0 for just storage.

no single GPU could saturate PCIE 4.0
