Hi,
I'm looking to improve my speakers on my new pc. at the moment I've got some old harmen / kardon stereo speakers from an old dell pc and quite frankly they dont do the job.
I'm using a Gigabyte GA-X48T-DQ6 Intel X48 (Socket 775) PCI-Express DDR3 Motherboard onboard audio. whats the best I can expect using just that and also whats a good speaker / sound card combo should i decide to upgrade the sound spec as well.

EDIT : the onboard audio is Audio Realtek ALC889A codec High Definition Audio 2/4/5.1/7.1-channel
