   I tried that.  Seems that the limitation isn't the CPU clock cycles, 
it's the pitiful cache that AMD put on the chip (128K L2 and no L1).  
Basically, the CPU spins its wheels waiting on data.  More wheel 
spinning isn't going to help.  :-(

Also, that mobo has only one stick of DDR400 memory.  Would there be any 
advantage to a second stick?  (Other than more ram, of course.)  The 
system has 512MB RAM.  If I can improve performance for < $100 well 
enough to run HD, I'll be happy.
