You'd be suprised how much money your spending on these systems to run on and off DX Gaming tests the major current past and next gen consoles and you'll be suprised who 1up's the xbox's processing power and energy consumption.
have you ever read the article or are you on drugs (bashing without reasons!)??? in stand by mode it take near the same. when you are playing the xbox360 it needs far more supply then the ps3.
I was surprised to read the PS2 used the same as the Xbox360, I hate to think how much the PS£ is going to use!
