They are the same silicon - both E6 stepping.
The FX60 has an unlocked multiplier which is an advantage I guess.
I;d just get the cheapest I could find and proceed to overclock it.
There is a new article on the front page which suggests getting a dual core up well over 2.4Ghz along with a decent graphics card (like a 4850) makes a much better gaming proposition for you.
Might be hard t ofind one cheap.
Will breath quite a bit of life into the 939 system.
Otherwise your up for an expensive upgrade as the mobo can't do AM2 stuff, and the RAM is DDR - not DDR2 used in later systems.
Alternatively if you can get a lower end Opt and overclock it ...
Good luck and I hope this helps !!
