I think I'll take back the comment I previously made. Clock speed(mhz) doesn't really show its actual performance. Take computer CPUs for example: a 2.2ghz(2200mhz) AMD CPU has the same performance as a 3.0ghz(3000mhz) Intel CPU even though AMD has a lower clock rate. Right now nobody knows what the Wii is capable of and only time can tell.
