Reading is not your strong point here is it!
The 750FX is FASTER than G4 at same clock WITHOUT Altivec. That is what was said.
Also, I think you miss the point about these MicroA1's. Mini ITX boards have never been about powerhorses with fast processors, fast video and the like.
The MicroA1 is about doing things well, silently and small with low power consumption just like a VIA Epia and the like. The 750FX can do that and the G4 can not.
If you want a power horse, you need the XE or XC.
EDIT: I have a 750FX and am only going to upgrade it if the 1.4 GHz G4 becomes available.
