For gaming+movie and a little bit of music, what 5.1 system choice should I look into?

Thinking of getting a new set of 2.1 speakers. So far I hear good comments on the S330. Ok here's the problem, at my place I can't seem to find anywhere have this up for demo. How is the S330 compared to Promedia 2.1 GMX?

The Promedia 2.1 GMX is going for RM410 at a store in my area. So was wondering how does this 2 compare. I have heard how the GMX performed and would like to know the differences between this 2.

EDIT : S330 and S330D what's the difference? i went to edifier's website and saw this 2 models that look alike.
