Any expected performance loss with this setup?

Because the 2080Ti already suffers from PCI-E Gen3x16 -> Gen3x8, I suppose the newer cards will require more bandwidth in order to be fully utilized to their full potential?

I have a 10900K system with Maximus 12 Apex, and according to this publication ASUS doesn't actually fully support PCI-E Gen4 for some reason: https://wccftech.com/z490-motherboards-pcie-gen-4-support-detailed-asus-msi-asrock-gigabyte/


Thoughts appreciated.
 
Are you serious ?
Everyone know that Intel mobos will not support PCIe 4.0 till next generation.

Speculations for PCIe difference between 3.0 and 4.0 from last few days are 5-7% difference based on current hardware (5700 XT) and software (Horizont Zero Dawn + few more) but we can wait and see.
But the AMD show different things here before few years:



But this is just nothing, we can only waiting what this companies will show in next few months.

some boards advertise pci-e4 operation with comet lake gen11 GPUs

asus is the only one who doesn't explicitly, and there's some hardware that's absent on asus boards for pcie4 functionality, which makes me concerned
 
Surprised this link was not put out. Some surprising results with newer games pushing pcie bandwidth.



When you see the 5700XT benefitting on newer games, makes you wonder what will the 3090 difference be.
 
Its going to be a tough comparison until intel has pcie4. For example, current intel generally out paces amd, although not by much, in pcie3. We will have a hybrid of pcie4 in a "slower" amd and pcie3 in the "faster" intel.
 
I suppose that we will see in next gen cards the difference through PCIe 4.0 and software in next year will show benefit from it too.
 
The question is not can you plug it in 3.0 - you can plug it into 1.1 slot and it will work but at what cost of performance ? :)

dude, should've went with a Ryzen setup, if you wanted PCIE 4. The main thing with that is, is if you're gonna be using high bandwidth NVME SSD's and a high end gpu, then you're gonna want your devices running on the pcie4 bus.
