As of late, a couple of the newer 360 games have been freezing on my machine. My machine is one of the first models..Hitachi V47. ANyway, i wondering with the new Elite 360 or the newer 360, if they have replaced the processor chips, and made the machine more powerful to handle these newer games that are requiring more power.. wonderin if i should sell my older 360 and maybe go buy a newer version, with a better processor chip, and hdmi.. or they still basically the same.. ????
