Who really has the better graphics?

[metra]

Okay im sorry if this has been posted before but I have a serious question. Who really has the better graphics of the 2 systems. I own a ps3 so im not biased at all. I' m starting to see that all 3 of gamespots graphical comparisons have the Xbox 360 showing better graphics.

 

I have also came across a few articles that sites and developers has stated that the xbox 360 gpu is superior to the rsx.

 

Mostly all the game trailers videos have showed that Xbox 360 having the better graphics

 

So i have a few questions..

 

Is it true that 360 GPU is superior to that of the PS3 RSX?

Does blu-ray have any affect to graphics like it does to movies??

Is the excuse true that all ps3 owners use which is that they make a game for 360 and port it over to the ps3?

Are multiplatform games always going to look better on 360?

And finally, everyone knows that ps3 has a powerful cpu called the cell but does it help contribute to the graphics and making the gpu more powerful than the 360?
