the mhz dont matter but the problem is that intel is releasing processors that are faster than the g4 now mainly that the g4 is updated really slowly, if apple released them like intel does, g4 would be so far ahead, but hte dual 800 has been around for a long time, they need to make large leaps and bounds in processor speads really badly or the g4 wont hold up to the pentium 4 top speed since it gets updated so fast. Apples hardware will be the lower end of computers if they dont keep up and update teh processors better...
