I would. There are practically negligible gains to be had from PCIe 4.0 at this point anyhow, and PCIe 4.0 is the only REAL difference between those chipsets in the long run anyway. So far pretty much all testing indicates little to no gains from it in gaming with PCIe 4.0 capable graphics cards or in storage device testing either. It took years for PCIe 3.0 to make a difference, I don't expect it to be any different this time around.I'd not buy a B450 at the end of 2020 anyway.
B550 is an odd chipset. It’s so darn close to X570 in features that it’s nearly the same price. As others have said there is virtually no gain from pcie 4.0 so the cheaper B450’s are a very compelling offer. I’ve seen reviews of B450 boards running 3950X’s as well as a X570 at stock settings. I doubt the majority of Ryzen users would loose anything by going with a high quality B450.I'd not buy a B450 at the end of 2020 anyway.
For some one who upgrades every 4 years PCIe 4.0 is a must today... even if the gains are little at the moment.I would.

You are focusing in GPU only , GPU does not need Gen 4 , 16 lanes Gen 3 is still enough and not saturated .Why would something that offers no benefit be "a must"? I keep hearing that it's a "must" but so far I haven't seen a single shred of evidence or any suggestion of proof as to why that would be.
Is there some notation somewhere that says the next generation of Nvidia or AMD graphics cards after Navi and Ampere are going to contain architectural improvements that are positively believed to see gains from the more robust bus? Is there some article indicating that there is going to be a determined effort to revamp the APIs specifically to benefit combinations of PCIe 4.0 graphics cards? Is the next generation of motherboard chipsets KNOWN to be inclusive of multiple PCIe 4.0 M.2 NVME slots, unlike current chipsets that only support a single PCIe 4.0 M.2 slot per board? And when they do, will it even matter, since reviews don't show Gen4 storage blowing up any benchmarks really?
I mean, yeah, I'm sure at some point it will be beneficial, and when it is, it will make sense to want that on any board you choose. And when next I choose a board, maybe later this year, I probably will go with something that IS PCIe 4.0 capable, but it's not going to be BECAUSE of that, and there are certainly a LOT more people out there that won't see any significant benefit from a PCIe 4.0 capable chipset over one that has everything else that board has except for that, than there are people who will. And I imagine it is going to remain that way for a long time.
Even people with the top shelf flagship GX cards aren't going to see much from it, and those people are in the very, VERY small minority of consumers anyhow.
I did read it all . and I think it is you who are not getting my points . which surprises me.No, I'm not. I specifically called out storage devices, so obviously you are not even bothering to read the whole post before reacting to it. Which I don't think surprises anyone.
The only SSD add in cards I've seen that are x8 are adapters that allow you to use multiple M.2 devices in a single slot. If you want to use multiple M.2 drives in a single slot you're still going to need a x8/x16 AIC adapter, regardless of whether it's PCIe 3.0 or 4.0.I said that storage CARDS and not NVME M2 will appear soon and will need the more bandwidth . that is 4 lanes gen 4 cards will replace 8 lanes Gen3 SSD cards which is HUGE because 8 lanes slots are rare to find at entry level unlike 4 lanes slots.
We're still a long way from saturating a PCIe 3.0 x1 interface with wifi (in actual achievable throughputs). I agree getting 10GbE adapter with a x1 slot could be handy, although I don't think any 10GbE PCIe 4.0 x1 cards are available yet. As far as >10GbE, I really don't see anyone having that on a mainstream PC in the next 4 years. Even 10Gbe is still rare and expensive compared to GbE.Gen 4 PCIexpress are important for add on cards , LAN cards , Nvme cards (not m2 , CARDS) , future Wifi cards , USB 3.2 2x2 cards , thunderbolt cards , etc
You cant manufacture 10Gb/s cards using single lane on Gen3 but on Gen 4 it is possible. and in 4 years we might have 20/40/100Gb lan card as well whhich needs the bandwidth.
