Well let me first start off by saying my brother wants to get a 360 slim, I have a 360. we both share a internet connection of 12mb and 678k upload. Im scared if he gets it it will cause lag on my and his end since games use upload speed. he will connect wirelessly and Im connected wired. He wants to play MW2 and me Bad Company 2 or my copy of MW2. Any advice? I was thinking of upgrading to 2mb upload if that helps.
