There's been alot of talk about the Jasper motherboard, but do the new xbox 360's have them? I have always wanted a 360 but was never willing to purchase one with all their reliability issues. Have the overheating problems with the 360 been solved? I've read many articles that stated the 360 is now being manufactured withe the Jasper? Is this correct, and when did Microsoft start installing the Jasper in the 360? If I buy a 360 how will I know if I have a Jasper?
