Gigabyte GA-7ZX Overclocking Possibilities?

I've got a Gigabyte GA-7ZX and would like some advice on how to overclock it. What CPU should I get (best value price/performance)? Is there any way to boost performance other than raising FSB with this board? I'm just begining, so I need lots of help and suggestions.

Thanks in advance,

1.4ghz athlons are easier to overclock than xps as they come unlocked the choice is urs.
