My girlfriend won two xbox 360's and 10 games from a tv competition pretty swish. We are going to keep one in the box cause it had a special case from some singer im not sure who it was. The second one we are selling to a family friend of ours. Now myself I already have an Xbox with an extended warranty for 5 years. But my Xbox doesn't have the hdmi port or I think the updated chip set and cooling. Do you think its worth swapping my Xbox for one of the other ones? Bearing in mind that i would loose my extended warranty and cause these xboxs were from a competition i dont have any documentation for warranty for them so im not sure what happens if it breaks... Is it worth it for a Hdmi port and updated chip set?
