So you are saying that the 360 is a lot less powerful than my brother's pc, and yet my brother's pc gets outperformed by the 360?
I see you mentioned the power of the 360 being compared to a laptop. My laptop is just a year old, with an intel dual core @ 2.83 GHz with a 1066 FSB. It's also got 4 GB of ram, and a 512 Mb Nvidia Geforce 9600M GT (DDR2). My laptop also gets outperformed by the 360...
So there is no reason to get into some argument over which is more powerful (given the ability to upgrade a pc). My argument is just supporting what kal326 said. The xbox 360 has the ability to outperform machines with equal and in some cases better hardware due to it's highly optimized code. My evidence for this argument is just what I know about my 360 (based on what tony told me), my laptop, and my brother's pc.
Now if you want to spend decent money on current components, than sure the 360 will not be able to compete. But that is not the argument here.
