Good 2.1 sound card?
Get Asus Xonar STX, which will cost ~7K.
@ Arnab ......It will be a waste. A 2.1 speaker that costs Rs 22000 or less will never do justice to that audio card.That dosnt mean the Swans are less of a speaker but they are not out an out studio monitors where details in a soundtrack scores over entertainment.If you had a Dynaudio MC 15 or Swans M200MKIII or a Sonodyne SM 200AK which are not 2.1 or dont have a separate bass module would actually do justice to a hi end audio card with more than 123db s/n ratio.With those active stereo speakers you can actually make out the difference.I can go on in length regarding this. I own both kinda speakers 2,1 and Studio Monitors and trust me they are as different as chalk and cheese.You have wonderful & entertaining speakers and your upper limit should be Rs 4000 for a sound card, maximum you wont go wrong.
Don't get Xonar DG. It is a cheap card which is used as a suppliment to the onboard audio in most of the cases.
Xonar DX is good 5.1 sound card, but as your speakers are 2.1, get STX. You won't regret.
EDIT:
Could you please shed some light or post some links or benchmarks about the Xonar DG being cheap and at par with onboard audio, to back up your claim? Really I want to know. Its a forum right? Be responsible for what you say and Enlighten us.
For the price it is an astounding sound card.Rather than trolling.... Read them......
