I will moving house shortly to an area that can only connect up to 1 Mbps (we currently have up to 3 Mbps). My 2 sons play Xbox games on-line and I'm worried that the broadband will be too slow when we move. I went onto Xbox website but it doesn't say how much broadband speed is needed to play the games. Would welcome any help. Thanks, Cec. (They play war games like Call of Duty).
