PS3 is a good console. But modern PC is between 10-50 times quicker (dependant on the power of your graphics system). PS3 has a rather quick processor though. That's why a lot of computing in this game is made on central processor. PC processor is not 10-50 times quicker. More like 5. And it has nothing to do with ethernet.

Also forget those stories about "Full Potential" with a full potential of a fork you can teleport continents into other planets.
