When you run 3DMark, They do a GPU and CPU test.
I've got an Intel Core 2 Duo E6300.
When I ran my 3DMark06 CPU test, I got 1 FPS. ONE FRAME RATE PER SECOND !
Sure, the map was a bit more detailed (mountain map), but the lighting was definitely nothing like it was in that video.
Now, this is to "Entroper", I really hope your being sarcastic, your even lucky if that P3 can DISPLAY that picture =P.
In that video, they are rendering a detailed car, with multiple lightings shooting out at the car (and if you don't think lighting is huge, play Quake 4, get in a dark area, turn on the thing that shows your FPS, and then turn on your flashlight and you'll notice how much your FPS drops), and well as rotating the whole car, in 720P = 1366 pixels by 768 pixels.
Now, back to my 3DMark, if my Intel Core2Duo E6300 (Dual Core) clocked at 1.8Ghz ran that graphic CPU test at 1 FRAME RATE PER SECOND, and the 3 PS3's core ran that image, MAINTAINING a smooth as hell frame rate per second, PS3 is one beautiful beast.

Just my 2 cents =]

Just think we could stack 1000 PS3s on top of one another and we could make the entire world into virtual reality! It would be like the Matrix! ZANG!!!!
