Firewire Cards

I’m running two MR816CSX daisy chained together and thinking of adding a third. Is there a difinitive answer to which PCI Firewire card works best with Yamaha FW Driver and these units? I’d just as soon find one that won’t give me any issues and buy it so… what should I be looking for? Thanks any and all.
