Overclocking Guide.

[ComputerNerd]

At the moment I am using a system with an AMD Phenom II X4 810 clocked at the default 2.6GHz, but wow is suffering badly performance wise being tolerable in 10 mans, but awful in wintergrasp/25 mans.
At least the general opinion seems to be that CPU is substantially underpowered, and the favourable upgrade to an i5 is outside of my budget.
So is there a good guide someone would recommend for overclocking so I can at least try to squeze a bit more out of that and get an idea whether the cheaper option of just a faster clocked AMD would be sufficient.

Although I think that processor should be able to pull 10 man, without much of a hassle to start with.
