2x GPUs Speeds on x570 Chipset?

The second PCIe x16 slot only has 4 lanes available. The first x16 slot has all 16 lanes. For the best performance, the main video card must go to the first x16 slot.

 

PCIe version doesn't matter anyway, both cards are PCIe 3.0 and that's how fast each lane will talk.

I have added a second GPU for auxiliary monitors, but I can't figure out the speed of the PCIe slots. I would prefer to install my main GPU in the second PCIe slot for better air flow and the auxiliary GPU in the first PCIe slot. Can I get PCIe 5.0 speeds on both PCIe slots with two GPU?

Ahh, thank you for clarifying that. I wasn't sure what it meant in the specs. Much appreciated. This link explains it better.
