i agree completely with gm9
some of the other little tips you can use to help speed up your machine is 1 better cpu/motherboard . associate other programs with other other cores like if you open web pages and use photoshop and WMP at the same time make them use a different core .

also increasing your ram helps ( to a point and depending on what you have type and speed and if you are running xp or vista)

also keeping EQ installed on a seprate HD keeps it from getting less fragmented(some people think they are getting video lag when they are really getting paging lag)
