What would be the "effect" of putting an RTX 3060/3070 into - PCI_E3: PCIe 4.0 x4...?

 

Instead of PCI_E1: or PCI_E2.

 

Thanks!

3060 at 4x you might be able to get away with without losing performance. With the 3070 I think you would definitely see a noticeable drop

It would run slower. So be less performant.

So...

 

If I were to go with the 3070 and put it in 3rd slot...

 

Would I be getting worse/about the same/better... performance - than if I went with the 3060 and put it in the 1st slot...?

Why would you put your faster card in a slower slot? The performance will be a bit all over the place and it cannot be flat out compared.

Your GPU will run normally but you will see a drop in performance due to less bandwidth available to it. Unless you have something else that requires a lot of bandwidth (for example a high end network card - a dual-port 100Gb Ethernet card can easily eat up a whole PCIe 3.0 x16 interface) you usually should not do this.

4x4 is going to see a drop 4x8 or 3x16 would be pretty minimal.  You will probably see less frequent drops with a 12GB card vs one with 8GB (depending on the game).

Then for both cards I advice you put then in the x16 slot
