Recommended Internet Connection Speed for 360

iv'e actually never gotten around to play Live :lol: and im wondering would it lag terrible with (1435 kb/s Download) (318 Upload) the server that gave me these result was 75 miles away from me should i upgrade? or is the connection good enough im assuming i got to upgrade! Tougths?

recommended internet speed: as fast as you can get.

i don't know the speeds i need ping numbers.

I'd say over 1MB?

Or Broadband really.

4MB is great though.
