This is just a stab... but last year I bought a desktop Athlon 64x2 
and had the opposite problem... it was *extremely* fast... never had 
a more responsive computer in my life.  In my case, the downside is 
that my clock was also fast... the clock ran about three times faster 
than it should (i.e. in one "real" minute, three "computer" minutes 
had passed).  After much searching, I found it had to do with 
interrupts... there was something weird about my chipset (it was 
pretty new at the time).

The 'fix' for this was an upgraded kernel and some kernel parameters 
set via grub.  Even if your problem isn't anything to do with 
interrupts, perhaps try a kernel upgrade or downgrade...

Good luck,
Roberto
