Adding new graphics card to existing OCLP install

I have a Mac Pro 5,1 running Sequoia with OCLP. It has the bog standard Radeon 5770.

I recently bought a new Sapphire RX 580. Would I just swap those cards or do I need to do a full OCLP install again. Just wondering about the root patches.

Cheers
