I tend to stick with Creative. I think that they have a decent quality, and that their prices on their mid to high level products are decent. Their top end products are just that, top end, and the price reflects it.HERE
is a decent 7.1 surround sound from creative. Now, this is somewhat mid level. It's not going to blow your socks off, but it'll sound good turned up fairly loud. Frag grenades and space ships will be all around you, sounding loud and clear but not making your ears bleed. Cranking it all the way to max volume will most likely distort it. If you want something that you can crank and hear a mile down the road, you can try these HERE
. These are a total of 700Watts of powere with a 210 Watt subwoofer. These may cause cranial fluid to drip from your ears
They'll also put a strain on your checking account at $499
You'll also need a good sound card to run a suround sound system and get decent sound. HERE
is a good gaming sound card. Please feel free to read all the specs on all of the links I've provided so that you can make an educated decision when buying your speakers and/or soundcard.
Personally, I'm a gamer too. IMHO, I don't need all the 7.1 surround speakers, and the top of the line sound cards, and thumping base that'll make your heart skip a beat. I've got a 4.1 surround system with a $30 sound card from Walmart (speakers and sound card are both creative labs though), and I'm more than happy with it.
Something that you have to keep in mind is that you'll have to run wires to all of your speakers, and you'll need someplace to put them, either a shelf or mount them on the wall or buy each speaker it's own stand. You might get sick of the wires all over the place (I know that I do). I'm actually going to purchase a nice set of 2.1 speakers that are high quality, so I can crank it, and have it sound great. I'll keep my current sound card, as it works fine.
Hope this helps!
