Question: "The extra time it takes to install the game on the PlayStation 3 doesn't seem to give the console any benefits over the Xbox 360" Do you really have to install the game on PS3?

Not bad at all. Comparing 3870 X2 to the similarly priced 8800 GTX, X2 wins nearly all the category besides COD4. Besides, it's even a bit cheaper. I think I'll take an X2 over 8800 GTX :-)
