plus the ps3 system has 8 cores to help the system push out power if i remember correctly and it has 2 teraflops for graphics. Where as the xbox 360 has only 4 cores and 1 teraflop of graphic power. So all in all what this means is that if a game were to come out on both systems the ps3 version would have to be dumbed down in order to be almost an exact copy of the xbox system. in short the 360 doesnt put out that much power. But there are only some games that I'll even play on it like Left 4 dead and Dead Or Alive 4
