It depends on the socket. If your motherboard takes Socket 939, you can probably upgrade to most newer processors. I'm pretty sure that even the previous socket (don't recall it's 'name') can have faster processors...
However, you should also check what chipset your motherboard uses too, it's possible there may be a dependency there, although depending on the board / processor combo, a BIOS update may help you upgrade further. I have an s939 nForce4 mobo, safe in the knowledge that I can and will be updgrading to a fast dual core as soon as they drop under £100.
Thanks to the rest of you re: not bothering to OC. I must admit to being sceptical myself, but wondered what other's experience was.
