Is it "OK" to use a low end NIC for a dedicated heart beat between two servers?

heartbeat

I've got nice big server-grade NICs on my servers busy interfaces. Soon I'll be setting up a cluster that will have a dedicated heat-beat.

Do I really need to use an expensive server grade NIC for this? Or will a low-end desktop NIC suffice?
