Currently im using a Turtle beach 5.1 analog which is very good. However I am extremely interested in the new Razer Tiamat 7.1 headset which is even better. Would be worth while to take a look at it. Shame its out of stock.. They had a really poor launch stock.. but oh well. here is links for both.

Im a big fan of having a sound card and doing analog!
