GCM vs CBC

Hi,

I've been replacing my routers and they have the option for Site-to-Site VPN to do GCM for phase 1&2. I've read my vendors documentation that states and they say on some models you may see a performance increase. General searching indicates that GCM may use more CPU.

What are peoples thoughts on switching to GCM? See any performance increase or other benefits?
