if ur upgrading make sure ur gettin better speakers before anything
ur new sound card will pump out all the numbers .. but whats the point if ur output from ur speakers is crappy ??
there will not be any significant gain ...
so i suggest u try better (5.1) speakers first ... ull get the "more punch and clarity" ur lookin for
let me put it in the simplest of ways
u have the best graphics card ... but u have a monochrome monitor
see what i mean ?
( i pick graphics as an example cuz everyone seems to understand that these days .. ofcurse the above situation is only hypothetical )
