I don't know why everyone makes a big deal about Altivec. Cell has more floating point power than 360 and even PS2 had more floating point power than the original Xbox and we see where the better games are, don't we?
That doesn't really make sense. Altivec is just one variant of SIMD/Vector processing or whatever you want to call it. Probably every game written on every console you mentioned uses vector processing to speed up execution, usually significantly.
