I've been researching and many Xbox 360 lovers keep pointing out that the PS3 supposedly does not have more powerful graphics processing than the Xbox360 due to the GPU being inferior.

But now I've come across information that the Cell is not your typical CPU and that it can actually take a lot of work away from the RSX (the RSX can offload work to the PS3's SPUs). So the PS3's Cell can calculate and process graphics?

I heard that originally the PS3 was not even supposed to have a GPU but only the Cell doing all of the work.

So how does it work? They can just use the seven 3.2 GHZ SPEs of the Cell for anything they want to? Graphics? Physics etc.?
