Edge Router for 1 Gbps

I am considering subscribing to a 1 Gbps cable modem service. I currently use a GLI B1300 as my edge router. Has anyone tried to run a B1300 with that WAN speed? For now, I am not looking for VPN performance, just basic routing.

What sort of performance if I upgraded to a Brume on a 1 Gbps connection?

How can I learn about other, higher-end options?

If you use for normal router, may just keep B1300.

You can consider our B2200 which will be shipped soon.
