I'm currently helping build out a new office and trying to find the best router for the job. My main concern is ensuring it can handle the WAN line(s) we have coming in. When I looked at the 2921 series it seems to have a throughput max of 75Mbps and with our lines totalling 800Mbps I'm wondering how 'big' of a router we'll need.
Here's some of the details that should give a rough idea of our needs. Our requirements are pretty basic at the moment but we would like to start to build our a reliable network infra as we're quiclkly expanding the business (20 -> 60 employees in 6mo thus far)
300Mbps 1:1 - BT Fibre
100Mbps 1:1 - Virgin
100 person max office size
2-3 VPNs into datacentre's
eventual deployment of our own VoIP network (currently managed by buildings VoIP)

Hi Steve,
as per the below guide
3925 about 429M
3945 about 500M
however if you have big amount of encrypted traffic this calculation might differ

another option you cloud consider is Cisco ASR1000 serise routers
hope this help

Thanks for the information. This confirms some suggestions by a few service providers I've managed to get in touch with today. Another option we saw was the 7301 despite it being EOL'd. The ASR1001 is a bit above our initial budget and doubtful I can make the case for substantial increase in costs.

Attachment has good performance information for the current ISRs.
If you're going to have WAN Ethernet handoffs, L3 switch might be an option.
PS:
BTW, the 7301 you mention is 1 Mpps (and a 7201 is 2 Mpps).
