you'll notice it when you really want speed (3d stuff, video editing converting and playing etc
For 3D stuff I prefer a T&L unit on the graphics card...
Don't tell me that Altivec is useless please
Huh? Where did I say so? I just said that the 750FX is faster than an equally clocked 7451/7455. IBM CPU's
are the better PowerPC's. I am anxiously waiting for the day that they integrate their 970 Altivec unit into the 750 design.
(now slow and expensive) G3s
Again, a "G3" (I still hate that stupid numbering scheme, it's like a Mot 750 and a 750FX are the same thing) is not slow. The 750 FX has twice the L2 cache than the 7451, and you *will* notice that.
A new G4 cpu is cheaper than 170pounds
Honestly, I don't know. But you need to complain to Eyetech not to me.
