A little Tidbit-
The graphics chip inside the X-box 360 is done by ATI this time. This means it will be far less powerful in that field, and it will be not near the amount of power that Nvidia could put in it. An interesting fact is that Nvidia is still making money off of the 360 even though they aren't involved. ATI doesn't have the skills to create the graphics shaders to fit the 360, so they were forced to pay Nvidia for their patented shader tech.
