I have a msi b450 tomahawk with a ryzen 1700 and a sapphire rx580 4gb nitro+ and my psu is a seasonic focus gold + 650w.

I have a spare r7 370 laying around could I put this into the bottom pci lane for crossfire?

Or stupid question?

Technically Crossfire as a name no longer exists. AMD has replaced it with Multi-GPU (or mGPU). And they only support it with two cards.

AMD used to have a compatibility chart for which GPU's can be mixed together. But the link is broken for it now. But I am pretty sure those two cards can be used together as they are in the same family.

However, the number of games that can utilize multiple GPU's is getting smaller ans smaller. So before you go and try it, see if any of the games you play are supported.

EDIT: I misread the secondary card as 570. With it being a 370, they are not compatible.

The r7 370 and RX 580 are completely different cards. I don't think you can CF them. You likely could get another RX 580 and CF it with the 580. Should be same memory size.

I totally misread that as 570. Memory size doesn't have to be the same though, the card with the least amount is what the card with more will use. So if you have a 4GB and an 8GB, both will only utilize 4GB.
