Highspeed Broadband Router

My company is going to be using a cable modem with a 3 Mega Bit pipeline to access the internet. I was wondering if anyone knew of any specific routers that would be more adept at handling these speeds. I know that not all routers are the same, I am just not sure if some are better at handlign higher speeds than others. If anyone could help me out this would be much appreciated!

Thanks!
