Processor: i5 12600kf

Graphics Cards: RTX 3090 and RTX 3050

I have the MAG Z690 TORPEDO motherboard. This board has 3x PCIe x16 slots, as follows:

PCI_E1 (From CPU)
Supports up to PCIe 5.0 x16

PCI_E3 (From Z690 chipset)
Supports up to PCIe 3.0 x4

PCI_E4 (From Z690 chipset)
Supports up to PCIe 3.0 x1

I want to use the RTX3090 for machine learning processing only and the RTX3050 for rendering computer video.

My question is in which slots do I put the video cards and what are the pros and cons of each slot for each video card?

OBS: I don't use the computer to play games, only to work.
 
If you have no other expansion cards, put the highest performing card in the highest performing slot, then work your way down. It likely wouldn't make a difference, maybe except if you used PCI_E4, but that depends on how much data is going back and forth between the video card and the system.
