Depends on the hardware you have, i see that you are using previously a USB headset, do you have a discrete good soundcard or only the mainboard chipset?, also want simulated 5.1/7.1 or true 5.1?
Only for games, also for music, films?
I use currently a Roccat Kave 5.1 with a Asus Phoebus, the headset are in your price range and i'm very pleased with them but they are analogic and you need a good souncard to power them.
