What is the best speaker set-up for gaming?

[TwIce]

Well, it seems that all but the most high end 5.1 systems (like this, which is too pricey for me) are of suspect quality, like this. They are suspiciously cheap and there is little to choose from, as PC gaming audio has now migrated to "home theater" systems with their own fancy speaker set-ups including amps, boosters, etc. All I want is good PC audio that will run off my sound card. 2.1 systems appear to be of much higher quality -- certainly better for music -- and I'm hoping the quality compared to the 5.1s and their "spatial" output will make up for the lack of rear speakers. I bought this system, top of the line for Logitech 2.1 PC speaker systems. I like logitech; I own a lot of their hardware and peripherals and find the quality to be uniformly high.
