I tired overclocking once a good while back.  It just wasn't worth it. 
By the time you fix everything that gets broke, it just isn't worth that
extra single digit percentage point of gain.  You run the risk of having
memory issues which can lead to bad data on the hard drive.  Then that
leads to more issues and this just keeps going in circles.  At some
point, it is going to fail and you could loose data that you don't
really want to loose.  There is also the heat issue as well. 

Also, I used to run foldingathome.  It does not do well with
overclocking.  It will error out pretty quick.  I tried this on a Abit
NF7 v2 mobo.  At that time, they were pretty much the king of
overclocking.  I bought everything intending to overclock but it wasn't
worth it.  I had a HUGE copper heat sink on that CPU.  I wonder what the
scrap value of that thing is?  lol 

Save up, buy a faster CPU or just do a upgrade.  Make a router out of
the older box, if it doesn't pull to much power.
