It is true that the xbox 360 had problems with overheating but when the xbox slim came out those problems where alomost erased but the xbox has hardly ever had performance problems as the ps3 has had terrible problems EX(I was playing COD Black Ops and almost every time on every missin of the story it would glitch and lag offline) and not to mention the terrible security of them being hacked over and over i think i mad my point
I still go back to my original Xbox that i got whenmit first came out it runs as if it was new
