Can try Sound Blaster X-Fi 5.1 USB around RM230 and get a short USB cable for it.

Position your speaker in equilateral triangle to your listening position. The subwoofer works well under table, but try position it in between your satellites speaker and try move inward and outward to see which bass sounds more "blend in" to you, also try adjust the bass level while positioning the sub.

That one is good if you want good sound only, for multiple function X-Fi 5.1 USB still a good thing.
