Ok. You are looking at Cheap yet Good quality. I'd recommend Altect Lansing or Edifier. The rest you have to put in effort survey. To yield the best gaming experience. 5.1 speakers and a good sound card. Unless your SC can support 5.1 or THX. That way it should do it.

Depends on your budget actually. For your best buying encounter is you goto the shop and hear each individual speakers with your own ears. By telling you which model is good and good does not help.

Regarding the older model back in the early 90s the Altec Lansing 45.1 is the best selling model. Now all speakers have integrated and cut cost on the material.

I used to have a creative and now still using for my old computer which has been 10 years and the sound quality is still great.. Now using edifier, not bad in my opinion, great sound quality too...

Yes. Most of the people here ask how is this and that. As aforementioned it is best recommended to take the trouble to visit the shops and listen with your own ears for the best results. Haha people tend to be lazy some times and want to be spoon fed. It happen most of the time in forum around.
