Sound system especially for games

Which woofer system is best for playing games on.Which is budget one also.

1. depends on ur budget

2. i got creative's t6100. works great.

3. depends on which sorta input u want to give em, optical/coaxial/normal 3.5mm jacks

4. creative's megaworks systems are cool too if u wana shake the whole neighbourhood (at the cost of empty pockets). OR logitech's Z-5500 and the likes.

bottomline: decide ur budget first
